Round of uvm.h cleanup.

The poorly named uvm.h is generally supposed to be for uvm-internal
users only.

- Narrow it to files that actually need it -- mostly files that need
  to query whether curlwp is the pagedaemon, which should maybe be
  exposed by an external header.

- Use uvm_extern.h where feasible and uvm_*.h for things not exposed
  by it.  We should split up uvm_extern.h but this will serve for now
  to reduce the uvm.h dependencies.

- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use
  UVMHIST(ubchist), since ubchist is declared in uvm.h but the
  reference evaporates if UVMHIST is not defined, so we reduce header
  file dependencies.

- Make uvm_device.h and uvm_swap.h independently includable while
  here.

Fix kassert in lfs by initializing vp first.

Use a marker node to iterate lfs_dchainhd / i_lfs_dchain.

I believe elements can be removed while the lock is dropped,
including the next node we're hanging on to.

Just use VOP_BWRITE for lfs_bwrite_log.
Hope this doesn't cause trouble with vfs_suspend.

Teach lfs to transition ro<->rw.

Prevent new dirops while we issue lfs_flush_dirops.

lfs_flush_dirops assumes (by KASSERT((ip->i_state & IN_ADIROP) == 0))
that vnodes on the dchain will not become involved in active dirops
even while holding no other locks (lfs_lock, v_interlock), so we must
set lfs_writer here.  All other callers already set lfs_writer.

We set fs->lfs_writer++ without explicitly doing lfs_writer_enter
because
(a) we already waited for the dirops to drain, and
(b) we hold lfs_lock and cannot drop it before setting lfs_writer.

Assert lfs_writer where I think we can now prove it.

Serialize access to the splay tree with lfs_lock.

Change some cheap KDASSERT into KASSERT.

Take a reference and fix assertions in lfs_flush_dirops.
Fixes panic:
KASSERT((ip->i_state & IN_ADIROP) == 0) at lfs_vnops.c:1670
lfs_flush_dirops
lfs_check
lfs_setattr
VOP_SETATTR
change_mode
sys_fchmod
syscall

This assertion -- and the assertion that vp->v_uflag has VU_DIROP set
-- is valid only until we release lfs_lock, because we may race with
lfs_unmark_dirop which will remove the nodes and change the flags.

Further, vp itself is valid only as long as it is referenced, which it
is as long as it's on the dchain, but lfs_unmark_dirop drops the
dchain's reference.

Don't lfs_writer_enter while holding v_interlock.

There's no need to lfs_writer_enter at all here, as far as I can see.
lfs_flush_fs will do it for us.

Break deadlock in PR kern/52301.

The lock order is lfs_writer -> lfs_seglock.  The problem in 52301 is
that lfs_segwrite violates this lock order by sometimes doing
lfs_seglock -> lfs_writer, either (a) when doing a checkpoint or (b),
opportunistically, when there are no dirops pending.  Both cases can
deadlock, because dirops sometimes take the seglock (lfs_truncate,
lfs_valloc, lfs_vfree):
(a) There may be dirops pending, and they may be waiting for the
seglock, so we can't wait for them to complete while holding the
seglock.
(b) The test for fs->lfs_dirops == 0 happens unlocked, and the state
may change by the time lfs_writer_enter acquires lfs_lock.

To resolve this in each case:
(a) Do lfs_writer_enter before lfs_seglock, since we will need it
unconditionally anyway.  The worst performance impact of this should
be that some dirops get delayed a little bit.
(b) Create a new lfs_writer_tryenter to use at this point so that the
test for fs->lfs_dirops == 0 and the acquisition of lfs_writer happen
atomically under lfs_lock.

Initialize/destroy lfs_allclean_wakeup in modcmd, not lfs_mountfs.

Fixes reloading lfs.kmod.

In lfs_update, hold lfs_writer around lfs_vflush.

Otherwise, we might do
lfs_vflush
-> lfs_seglock
-> lfs_segwait(SEGM_CKP)
   -> lfs_writer_enter
which is the reverse of the lfs_writer -> lfs_seglock ordering.

Call lfs_orphan in lfs_rename while we're still in the dirop.
lfs_writer_enter can't fail; keep it simple and don't pretend it can.

Assert that mtsleep can't fail either -- it doesn't catch signals and
there's no timeout.

Teach LFS_ORPHAN_NEXTFREE about lfs64.

Dust off the orphan detection code and try to make it work.

Fix !DIAGNOSTIC compile

Fix userland references to LFS_ORPHAN_NEXTFREE.

Forgot to grep for these or do a full distribution build, oops!

Fix missing <sys/evcnt.h> by removing the evcnts instead.

Just wanted to confirm that a race might happen, and indeed it did.
These serve little diagnostic value otherwise.

OR into bp->b_cflags; don't overwrite.

CTASSERT lfs on-disk structure sizes.

Avoid misaligned access to lfs64 on-disk records in memory.
lfs64 directory entries are only 32-bit aligned in order to conserve
space in directory blocks, and we had a hack to stuff a 64-bit inode
in them.  This replaces the hack by __aligned(4) __packed, and goes
further:

1. It's not clear that all the other lfs64 data structures are 64-bit
   aligned on disk to begin with.  We can go through these later and
   upgrade them from
        struct foo64 {
                ...
        } __aligned(4) __packed;
        union foo {
                struct foo64 f64;
                ...
        };
   to
        struct foo64 {
                ...
        };
        union foo {
                struct foo64 f64 __aligned(8);
                ...
        } __aligned(4) __packed;
   if we really want to take advantage of 64-bit memory accesses.
   However, the __aligned(4) __packed must remain on the union
   because:
2. We access even the lfs32 data structures via a union that has
   lfs64 members, and it turns out that compilers will assume access
   through a union with 64-bit aligned members implies the whole
   union has 64-bit alignment, even if we're only accessing a 32-bit
   aligned member.

Fix clang build after packed lfs64 accessor change.

Suppress spurious address-of-packed error in rump lfs too.

Merge the remaining changes from the ad-namecache branch, affecting namei()
and getcwd():

- push vnode locking back as far as possible.
- do most lookups directly in the namecache, avoiding vnode locks & refs.
- don't block new refs to vnodes across VOP_INACTIVE().
- get shared locks for VOP_LOOKUP() if the file system supports it.
- correct lock types for VOP_ACCESS() / VOP_GETATTR() in a few places.

Possible future enhancements:

- make the lookups lockless.
- support dotdot lookups by being lockless and inferring absence of chroot.
- maybe make it work for layered file systems.
- avoid vnode references at the root & cwd.

- Add and use wrapper functions that take and acquire page interlocks, and pairs
  of page interlocks.  Require that the page interlock be held over calls to
  uvm_pageactivate(), uvm_pagewire() and similar.

- Solve the concurrency problem with page replacement state.  Rather than
  updating the global state synchronously, set an intended state on
  individual pages (active, inactive, enqueued, dequeued) while holding the
  page interlock.  After the interlock is released put the pages on a 128
  entry per-CPU queue for their state changes to be made real in batch.
  This results in in a ~400 fold decrease in contention on my test system.
  Proposed on tech-kern but modified to use the page interlock rather than
  atomics to synchronise as it's much easier to maintain that way, and
  cheaper.

Update the kernhist(9) kernel history code to address issues identified
in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in
   the kernel and in the structures used for exporting the history data
   to userland via sysctl(9).  This avoids problems on some architectures
   where passing a 64-bit (or larger) value to printf(3) can cause it to
   process the value as multiple arguments.  (This can be particularly
   problematic when printf()'s format string is not a literal, since in
   that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to
   include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings
   updated.  Each format specifier now includes an explicit length
   modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings
   updated to replace uses of "%p" with "%#jx", and the pointer
   arguments are now cast to (uintptr_t) before being subsequently cast
   to (uintmax_t).  This is needed to avoid compiler warnings about
   casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or
   "%c" format strings replaced with numeric formats; several instances
   of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the
   history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with
   the -u option does not exist (previously, this condition was silently
   ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the
   data exported via sysctl(9) and exits if they do not match the values
   with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional
   requirements imposed on the format strings, along with several other
   minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example,
     uint64_t) for the history arguments.  But that would require another
     "rototill" of all the users in the future when we add support for an
     architecture that supports a larger size.  Also, the printf(3)
format
     specifiers for explicitly-sized values, such as "%"PRIu64, are much
     more verbose (and less aesthetically appealing, IMHO) than simply
     using "%ju".
[2] I've tried very hard to find "all [the] existing users of
kernhist(9)"
     but it is possible that I've missed some of them.  I would be glad
to
     update any stragglers that anyone identifies.
--
For some reason this single kernel seems to have outgrown its declared
size as a result of the kernhist(9) changes.  Bump the size.
XXX The amount of increase may be excessive - anyone with more detailed
XXX knowledge please feel free to further adjust the value
appropriately.
--
Misssed one cast of pointer --> uintptr_t in previous kernhist(9) commit
--
And yet another one.  :(
--
Use correct mark-up for NetBSD version.
--
More improvements in grammar and readability.
--
Remove a stray '"' (obvious typo) and add a couple of casts that are
probably needed.
--
And replace an instance of "%p" conversion with "%#jx"
--
Whitespace fix. Give Bl tag table a width. Fix Xr.

Add byteswapping to the dinode accessors.

This prevents regressions in the ulfs code when switching to the new
accessors. Note that while adding byteswapping to the other accessors
is straightforward, I haven't done it yet; and that also is not enough
to make LFS_EI work, because there are places lying around that bypass
the accessors for one reason and another and all of them need to be
updated. That is going to have to wait for a later day as LFS_EI is
not on the critical path right now.

Use the lfs dinode accessors in place of the ufs-derived ones.
(Mostly.)

The ufs-derived ones are fake structure member macros, which are gross
and not very safe. Also, it seems that a lot of places in the lfs code
were using the ffsv1 branch of them unconditionally, and this way it's
guaranteed all those places have been updated.

Found while doing this: for non-devices, have getattr produce NODEV
in the rdev field instead of leaking the address of the first direct
block.

Hack up dinode usage to be 64 vs. 32 as needed. Part 1.

(This part changes the native lfs code; the ufs-derived code already
has 64 vs. 32 logic, but as aspects of it are unsafe, and don't
entirely interoperate cleanly with the lfs 64/32 stuff, pass 2 will be
rehashing that.)

Pass the fs object to LFS_MAX_DADDR so it can check lfs_is64.

Remove some hackish intentional 64->32 truncations next to the checks
using LFS_MAX_DADDR, and tackle the problem they handled in bmap
instead.

The problem: the magic block pointer value UNWRITTEN has magic value
-2, and if it's not handled specifically, uint32 -> uint64 promotion
turns it into 4294967294, which then causes consternation and
monkeyhouse downstream.

What's here is still kind of a hack, but it's a step forward.

Add an include of lfs_accessors.h after all uses of lfs.h... except
for code that wants to define its own struct lfs-alike that the
accessors are supposed to play along with. For these, set STRUCT_LFS
and include lfs_accessors.h after the necessary structure has been
defined, so that lfs_accessors.h can emit functions in terms of it.

Switch to accessor functions for elements of the LFS on-disk
superblock. This will allow switching between 32/64 bit forms on the
fly; it will also allow handling LFS_EI reasonably tidily. (That
currently doesn't work on the superblock.)

It also gets rid of cpp abuse in the form of fake structure member
macros.

Also, instead of doing sleep/wakeup on &lfs_avail and &lfs_nextseg
inside the on-disk superblock, add extra elements to the in-memory
struct lfs for this. (XXX: these should be changed to condvars, but
not right now)

XXX: this migrates a structure needed by the lfs code in libsa (struct
salfs) into lfs.h, where it doesn't belong, but for the time being
this is necessary in order to allow the accessors (and the various
lfs macros and other goop that relies on them) to compile.

Change lfs from hash table to vcache.

- Change lfs_valloc() to return an inode number and version instead of
  a vnode and move lfs_ialloc() and lfs_vcreate() to new lfs_init_vnode().

- Add lfs_valloc_fixed() to allocate a known inode, used by kernel
  roll forward.

- Remove lfs_*ref(), these functions cannot coexist with vcache and
  their commented behaviour is far away from their implementation.

- Add the cleaner lwp and blockinfo to struct ulfsmount so lfs_loadvnode()
  may use hints from the cleaner.

- Remove vnode locks from ulfs_lookup() like we did with ufs_lookup().

Limit check for 'data_len'. Otherwise a (un)privileged user can easily
panic the system by passing a huge size.
ok christos@
An (un)privileged user can easily make the kernel dereference a NULL
pointer.
The kernel allows 'data' to be NULL; it's the fs's responsibility to
ensure that it isn't NULL (if the fs actually needs data).
ok christos@
Some fs's - like kernfs - set their vfs_min_mount_data to zero. Add a check
to prevent an (un)privileged user from requesting a zero-sized allocation
(and thus a panic).
This thing is totally buggy: 'data_len' is modified by the fs, so calling
kmem_free with it while its value has changed since the kmem_alloc is far
from being a good idea.
If the kernel figures out that something mismatches, it will panic
(typically with kernfs).

Add lfs_kernel.h for declarations that don't need to be exposed to userland.

lfs currently has the following headers:
   lfs.h - on-disk structures and stuff needed for userlevel tools
   lfs_inode.h - additional restricted materials for userlevel tools
                 that operate the fs (newfs_lfs, fsck_lfs, lfs_cleanerd)
   lfs_kernel.h - stuff needed only in the kernel

and the following legacy headers that are expected to be mopped up and
folded into one of the above:
   lfs_extern.h - function prototypes
   ulfs_bswap.h - endian-independent support
   ulfs_dinode.h - now contains very little
   ulfs_dirhash.h - dirhash support
   ulfs_extattr.h - extattr support

   MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
   MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have

* Remove PGO_RECLAIM during lfs_putpages()' call to genfs_putpages(),
  to avoid a live lock in the latter when reclaiming a vnode with
  dirty pages.

* Add a new segment flag, SEGM_RECLAIM, to note when a segment is
  being written for vnode reclamation, and record which inode is being
  reclaimed, to aid in forensic debugging.

* Add a new segment flag, SEGM_SINGLE, so that opportunistic writes
  can write a single segment's worth of blocks and then stop, rather
  than writing all the way up to the cleaner's reserved number of
  segments.

* Add assert statements to check mutex ownership is the way it ought
  to be, mostly in lfs_putpages; fix problems uncovered by this.

* Don't clear VU_DIROP until the inode actually makes its way to disk,
  avoiding a problem where dirop inodes could become separated
  (uncovered by a modified version of the "ckckp" forensic regression
  test).

* Move the vfs_getopsbyname() call into lfs_writerd.  Prepare code to
  make lfs_writerd notice when there are no more LFSs, and exit losing
  the reference, so that, in theory, the module can be unloaded.  This
  code is not enabled, since it causes a crash on exit.

* Set IN_MODIFIED on inodes flushed by lfs_flush_dirops.  Really we
  only need to set IN_MODIFIED if we are going to write them again
  (e.g., to write pages); need to think about this more.

Finally, several changes to help avoid "no clean segments" panics:

* In lfs_bmapv, note when a vnode is loaded only to discover whether
  its blocks are live, so it can immediately be recycled.  Since the
  cleaner will try to choose ~empty segments over full ones, this
  prevents the cleaner from (1) filling the vnode cache with junk, and
  (2) squeezing any unwritten writes to disk and running the fs out of
  segments.

* Overestimate by half the amount of metadata that will be required
  to fill the clean segments.  This will make the disk appear smaller,
  but should help avoid a "no clean segments" panic.

* Rearrange lfs_writerd.  In particular, lfs_writerd now pays
  attention to the number of clean segments available, and holds off
  writing until there is room.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem

PR kern/38141 lookup/vfs_busy acquire rwlock recursively

Simplify the mount locking. Remove all the crud to deal with recursion on
the mount lock, and crud to deal with unmount as another weirdo lock.

Hopefully this will once and for all fix the deadlocks with this. With this
commit there are two locks on each mount:

- krwlock_t mnt_unmounting. This is used to prevent unmount across critical
  sections like getnewvnode(). It's only ever read locked with rw_tryenter(),
  and is only ever write locked in dounmount(). A write hold can't be taken
  on this lock if the current LWP could hold a vnode lock.

- kmutex_t mnt_updating. This is taken by threads updating the mount, for
  example when going r/o -> r/w, and is only present to serialize updates.
  In order to take this lock, a read hold must first be taken on
  mnt_unmounting, and the two need to be held across the operation.

One effect of this change: previously if an unmount failed, we would make a
half hearted attempt to back out of it gracefully, but that was unlikely to
work in a lot of cases. Now while an unmount that will be aborted is in
progress, new file operations within the mount will fail instead of being
delayed. That is unlikely to be a problem though, because if the admin
requests unmount of a file system then s(he) has made a decision to deny
access to the resource.

kern/38135 vfs_busy/vfs_trybusy confusion

The symptom was that sometimes file systems would occasionally not appear
in output from 'df' or 'mount' if the system was busy. Resolution:

- Make mount locks work somewhat like vm_map locks.
- vfs_trybusy() now only fails if the mount is gone, or if someone is
  unmounting the file system. Simple contention on mnt_lock doesn't
  cause it to fail.
- vfs_busy() will wait even if the file system is being unmounted.

  multiple file system mounts on the same device. It's no longer needed.

- Track opens by vnode and by device. Issue cdev_close() when the last open
  goes away, instead of abusing vnode::v_usecount to tell if the device is
  open.

Change the VFS_MOUNT() interface so that the 'data' buffer passed to the
fs code is a kernel buffer, pass though the length of the buffer as well.
Since the length of the userspace buffer isn'it (yet) passed through the mount
system call, add a field to the vfsops structure containing the default length.
Split sys_mount() for calls from compat code.
Ride one of the recent kernel version changes - old fs LKMs will load, but
sys_mount() will reject any attempt to use them.

Change references to SEGM_W_DIROPS to SEGM_CKP, and replace the logic that
formerly used SEGM_W_DIROPS in lfs_segwrite() appropriately.  This prevents
a problem in which processes could get stuck in "buffers" sleep forever.

Install a new sysctl, vfs.lfs.ignore_lazy_sync, which causes LFS to ignore
the "smooth" syncer, as if vfs.sync.*delay = 0, but only for LFS.  The
default is "on", i.e., ignore lazy sync.

Reduce the amount of polling/busy-waiting done by lfs_putpages().  To
accomplish this, copied genfs_putpages() and modified it to indicate which
page it was that caused it to return with EDEADLK.  fsync()/fdatasync()
should no longer ever fail with EAGAIN, and should not consume huge
quantities of cpu.

Also, try to make dirops less likely to be written as the result of a
VOP_PUTPAGES(), while ensuring that they are written regularly.

New file system suspension API to replace vn_start_write and vn_finished_write.
The suspension helpers are now put into file system specific operations.
This means every file system not supporting these helpers cannot be suspended
and therefore snapshots are no longer possible.

Implemented for file systems of type ffs.

The new API is enabled on a kernel option NEWVNGATE.  This option is
not enabled by default in any kernel config.

Presented and discussed on tech-kern with much input from
Bill Studenmund <wrstuden@netbsd.org> and YAMAMOTO Takashi <yamt@netbsd.org>.

Welcome to 4.99.9 (new vfs op vfs_suspendctl).

Changes to help the roll-forward agent, to wit:

* Mark being-deleted files in the Ifile so we can finish deleting them
  at fs mount time.
* Flag the Ifile with "cleaner must clean" when writers are waiting for
  the cleaner, rather than relying solely on the cleaner's estimation of
  whether it should clean or not.
* Note partial segments written by a user agent (in particular,
  fsck_lfs) so that repeated rolls forward don't interfere with one
  another.
* Add a new fcntl, LFCNPASS, that allows the log to wrap exactly once,
  for better testing of the validity of checkpoints.
* Keep track of the on-disk nlink count when cleaning, so that we don't
  partially complete directory operations while cleaning.
* Ensure that every single Ifile inode write represents a consistent
  view of the filesystem.  In particular, the accounting for the segment
  we are writing the inode into must be correct, and the accounting for
  the segment that inode used to reside in must be correct.  Rather than
  just rewriting the inode if we wrote it wrong, rewrite the necessary
  ifile blocks before writing the inode so we never write it wrong.
* Don't unmark any VDIROP vnodes if we haven't written them to disk,
  avoiding yet another problem with the "wait for the cleaner" error
  return from lfs_putpages().

Also, move the last callback to an aiodone call, so we no longer do any
memory management from interrupt context.

on vnodes that are being flushed, even if we don't think there's room;
drain v_numoutput before lfs_vflush() completes.
Also, don't allow a vnode that is in the process of being cleaned to be
chosen by getnewvnode(); this avoids a segment accounting panic in the case
that a large number of inodes are fed to lfs_markv() all at once.

Introduce another per-filesystem parameter, lfs_resvseg, to separate the
notion of "how many segments are reserved for the cleaner" from that of
"how many segments are not counted in lfs_bfree".  The default value
used for existing filesystems is the same as the previous implicit value
of (lfs_minfreeseg / 2 + 1), modulo some sanity checking.
Count pending dirops on a per-filesystem basis, since once we start
writing them we can't stop until we're done.  This seems to help stave off
the "no clean segments" panic in the case of filling the filesystem with
directories and small files (e.g. simultaneously unpacking more copies of
pkgsrc than will fit).

Improvements to LFS's paging mechanism, to wit:
* Acknowledge that sometimes there are more dirty pages to be written to
   disk than clean segments.  When we reach the danger line,
   lfs_gop_write() now returns EAGAIN.  The caller of VOP_PUTPAGES(), if
   it holds the segment lock, drops it and waits for the cleaner to make
   room before continuing.
* Note and avoid a three-way deadlock in lfs_putpages (a writer holding
   a page busy blocks on the cleaner while the cleaner blocks on the
   segment lock while lfs_putpages blocks on the page).

- remove GOP_SIZE_READ/GOP_SIZE_WRITE flags.
  they have not been used since the change.
- ufs_balloc_range: remove code which has been no-op since the change.
  thanks Konrad Schroder for explaining the original intention of the code.
- ffs_gop_size: don't extend past eof, in the case of GOP_SIZE_MEM.
  otherwise genfs_getpages end up to allocate pages past eof unnecessarily.

Double-checkpoint on unmount.  This ensures that vnodes belonging to removed

Improvements to LFS's paging mechanism, to wit:

* Acknowledge that sometimes there are more dirty pages to be written to
  disk than clean segments.  When we reach the danger line,
  lfs_gop_write() now returns EAGAIN.  The caller of VOP_PUTPAGES(), if
  it holds the segment lock, drops it and waits for the cleaner to make
  room before continuing.

* Note and avoid a three-way deadlock in lfs_putpages (a writer holding
  a page busy blocks on the cleaner while the cleaner blocks on the
  segment lock while lfs_putpages blocks on the page).

Apply the NFS exports list rototill patch:

- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
  function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
  file sys/nfs/nfs_export.c.  The former was becoming large and its code
  is always compiled, regardless of the build options.  Using the latter,
  the code is only compiled in when NFSSERVER is enabled.  While doing this,
  also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
  path and a set of export entries.  At the moment it can only clear the
  exports list or append entries, one by one, but it is done in a way that
  allows setting the whole set of entries atomically in the future (see the
  comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
  that it becomes file system agnostic.  In fact, all this whole thing was
  done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
  exports initialization; done internally by the kernel when initializing
  the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
  subsystems can run arbitrary code upon receipt of specific VFS events.
  At the moment, this only provides support for unmount and is used to
  destroy NFS exports lists from the file systems being unmounted, though it
  has room for extension.

Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments
and advice in the development of this patch.

Various minor LFS improvements.

Kernel:

* Note when lfs_putpages(9) thinks it is not going to be writing any
   pages before calling genfs_putpages(9).  This prevents a situation in
   which blocks can be queued for writing without a segment header.
* Correct computation of NRESERVE(), though it is still a gross
   overestimate in most cases.  Note that if NRESERVE() is too high, it
   may be impossible to create files on the filesystem.  We catch this
   case on filesystem mount and refuse to mount r/w.
* Allow filesystems to be mounted whose block size is == MAXBSIZE.
* Somewhere along the line, ufs_bmaparray(9) started mangling UNWRITTEN
   entries in indirect blocks again, triggering a failed assertion "daddr
   <= LFS_MAX_DADDR".  Explicitly convert to and from int32_t to correct
   this.  Should fix PR #29045.
* Add a high-water mark for the number of dirty pages any given LFS can
   hold before triggering a flush.  This is settable by sysctl, but off
   (zero) by default.
* Be more careful about the MAX_BYTES and MAX_BUFS computations so we
   shouldn't see "please increase to at least zero" messages.
* Note that VBLK and VCHR vnodes can have nonzero values in di_db[0]
   even though their v_size == 0.  Don't panic when we see this.
   Fixes PR #26680.
* Change lfs_bfree to a signed quantity.  The manner in which it is
   processed before being passed to the cleaner means that sometimes it
   may drop below zero, and the cleaner must be aware of this.
* Never report bfree < 0 (or higher than lfs_dsize) through
   lfs_statfs(9).  This prevents df(1) from ever telling us that our full
   filesystems have 16TB free.
* Account space allocated through lfs_balloc(9) that does not have
   associated buffer headers, so that the pagedaemon doesn't run us out
   of segments.
* Return ENOSPC from lfs_balloc(9) when bfree drops to zero.
* Address a deadlock in lfs_bmapv/lfs_markv when the filesystem is being
   unmounted.  Because vfs_busy() is a shared lock, and
   lfs_bmapv/lfs_markv mark the filesystem vfs_busy(), the cleaner can be
   holding the lock that umount() is blocking on, then try to vfs_busy()
   again in getnewvnode().

cleaner:

* Adapt lfs_cleanerd to use the fcntl call to get the Ifile filehandle,
   so it need not be in the namespace.
* Make lfs_cleanerd be more careful when there are very few available
   segments.
* Make lfs_cleanerd less verbose when the filesystem is unmounted.

newfs_lfs, fsck_lfs, and regression:

* Extend the lfs library from fsck_lfs(8) so that it can be used with a
   not-yet-existent LFS.  Make newfs_lfs(8) use this library, so it can
   create LFSs whose Ifile is larger than one segment.  Addresses PR #11110.
* Make newfs_lfs(8) use strsuftoi64() for its arguments, a la newfs(8).
* Make fsck_lfs(8) respect the "file system is clean" flag.
* Don't let fsck_lfs(8) think it has dirty blocks when invoked with the
   -n flag.
* Remove the Ifile from the filesystem namespace.  The cleaner now uses
   a fcntl call on the root inode to find the Ifile filehandle.  (As a
   side-effect, addresses PR #29144.)

Keep per-inode, per-fs, and subsystem-wide counts of blocks allocated through
lfs_balloc(), and use that to estimate the number of dirty pages belonging
to LFS (subsystem or filesystem).  This is almost certainly wrong for
the case of a large mmap()ed region, but the accounting is tighter than
what we had before, and performs much better in the typical case of pages
dirtied through write().

Keep track of the highest block held by an LFS inode, so that we can
be assured that the last byte of a file is always allocated.  Previously
a file extension could cause the filesystem to be flushed, writing an
inconsistent inode to disk.  Although this condition would be corrected
the next time blocks were written to disk, an intervening crash would leave
the filesystem in an inconsistent state, leaving fsck_lfs to complain
of an inode "partially truncated".

Use log(9) to warn the user instead of printf(9).  Since the theory is that

when the inode entries can't be held in cache, note these two cases
separately, at different log levels (notice and warning, respectively).

Various minor LFS improvements:

* Note when lfs_putpages(9) thinks it is not going to be writing any
  pages before calling genfs_putpages(9).  This prevents a situation in
  which blocks can be queued for writing without a segment header.
* Correct computation of NRESERVE(), though it is still a gross
  overestimate in most cases.  Note that if NRESERVE() is too high, it
  may be impossible to create files on the filesystem.  We catch this
  case on filesystem mount and refuse to mount r/w.
* Allow filesystems to be mounted whose block size is == MAXBSIZE.
* Somewhere along the line, ufs_bmaparray(9) started mangling UNWRITTEN
  entries in indirect blocks again, triggering a failed assertion "daddr
  <= LFS_MAX_DADDR".  Explicitly convert to and from int32_t to correct
  this.
* Add a high-water mark for the number of dirty pages any given LFS can
  hold before triggering a flush.  This is settable by sysctl, but off
  (zero) by default.
* Be more careful about the MAX_BYTES and MAX_BUFS computations so we
  shouldn't see "please increase to at least zero" messages.
* Note that VBLK and VCHR vnodes can have nonzero values in di_db[0]
  even though their v_size == 0.  Don't panic when we see this.
* Change lfs_bfree to a signed quantity.  The manner in which it is
  processed before being passed to the cleaner means that sometimes it
  may drop below zero, and the cleaner must be aware of this.
* Never report bfree < 0 (or higher than lfs_dsize) through
  lfs_statvfs(9).  This prevents df(1) from ever telling us that our full
  filesystems have 16TB free.
* Account space allocated through lfs_balloc(9) that does not have
  associated buffer headers, so that the pagedaemon doesn't run us out
  of segments.
* Return ENOSPC from lfs_balloc(9) when bfree drops to zero.
* Address a deadlock in lfs_bmapv/lfs_markv when the filesystem is being
  unmounted.  Because vfs_busy() is a shared lock, and
  lfs_bmapv/lfs_markv mark the filesystem vfs_busy(), the cleaner can be
  holding the lock that umount() is blocking on, then try to vfs_busy()
  again in getnewvnode().

Add a new flag, IN_MODIFY.  This is like IN_UPDATE|IN_CHANGE, but unlike
setting those flags, it does not cause the inode to be written in the periodic
sync.  This is used for writes to special files (devices and named pipes) and
FIFOs.

Do not preemptively sync updates to access times and modification times.  They
are now updated in the inode only opportunistically, or when the file or device
is closed.  (Really, it should be delayed beyond close, but this is enough to
help substantially with device nodes.)

And the most amusing part:
Trickle sync was broken on both FFS and ext2fs, in different ways.  In FFS, the
periodic call to VFS_SYNC(MNT_LAZY) was still causing all file data to be
synced.  In ext2fs, it was causing the metadata to *not* be synced.  We now
only call VOP_UPDATE() on the node if we're doing MNT_LAZY.  I've confirmed
that we do in fact trickle correctly now.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.

- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

Dynamic sysctl.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

Make LFS work better (though still not "well") as an NFS-exported
filesystem (and other things that needed to be fixed before the tests
would complete), to wit:

* Include the fs ident in the filehandle; improve stale filehandle checks.

* Change definition of blksize() to use the on-dinode size instead of
  the inode's i_size, so that fsck_lfs will work properly again.

* Use b_interlock in lfs_vtruncbuf.

* Postpone dirop reclamation until after the seglock has been released,
  so that lfs_truncate is not called with the segment lock held.

* Don't loop in lfs_fsync(), just write everything and wait.

* Be more careful about the interlock/uobjlock in lfs_putpages: when we
  lose this lock, we have to resynchronize dirtiness of pages in each
  block.

* Be sure to always write indirect blocks and update metadata in
  lfs_putpages; fixes a bug that caused blocks to be accounted to the
  wrong segment.

PR/1796: John Kohl: statfs misbehaves under chrooted environments.

- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
  and factored out some of the vfsop statfs() code to copy_statfs_info(). This
  fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.

Add code to UBCify LFS.  This is still behind "#ifdef LFS_UBC" for now
(there are still some details to work out) but expect that to go
away soon.  To support these basic changes (creation of lfs_putpages,
lfs_gop_write, mods to lfs_balloc) several other changes were made, to
wit:

* Create a writer daemon kernel thread whose purpose is to handle page
  writes for the pagedaemon, but which also takes over some of the
  functions of lfs_check().  This thread is started the first time an
  LFS is mounted.

* Add a "flags" parameter to GOP_SIZE.  Current values are
  GOP_SIZE_READ, meaning that the call should return the size of the
  in-core version of the file, and GOP_SIZE_WRITE, meaning that it
  should return the on-disk size.  One of GOP_SIZE_READ or
  GOP_SIZE_WRITE must be specified.

* Instead of using malloc(...M_WAITOK) for everything, reserve enough
  resources to get by and use malloc(...M_NOWAIT), using the reserves if
  necessary.  Use the pool subsystem for structures small enough that
  this is feasible.  This also obsoletes LFS_THROTTLE.

And a few that are not strictly necessary:

* Moves the LFS inode extensions off onto a separately allocated
  structure; getting closer to LFS as an LKM.  "Welcome to 1.6O."

* Unified GOP_ALLOC between FFS and LFS.

* Update LFS copyright headers to correct values.

* Actually cast to unsigned in lfs_shellsort, like the comment says.

* Keep track of which segments were empty before the previous
  checkpoint; any segments that pass two checkpoints both dirty and
  empty can be summarily cleaned.  Do this.  Right now lfs_segclean
  still works, but this should be turned into an effectless
  compatibility syscall.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

Deal with fragment size changes better.  For each fragment that can
exist on an on-disk inode, we keep a record of its size in struct inode,
which is updated when we write the block to disk.  The cleaner routines
thus have ready access to what size is the correct size for this block,
on disk.

Fixed a related bug: if a file with fragments is being cleaned
(fragments being cleaned) at the same time it is being extended beyond
NDADDR blocks, we could write a bogus FINFO record that has a frag in the
middle; when it was cleaned this would give back bogus file data.  Don't
write the indirect blocks in this case, since there is no need.

lfs_fragextend and lfs_truncate no longer require the seglock, but instead
take a shared lock, which the seglock locks exclusively.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

Pull up revision 1.77 (requested by perseant in ticket #325):
For synchronous writes, keep separate i/o counters for each write, so
processes don't have to wait for one another to finish (e.g., nfsd seems
to be a little happier now, though I haven't measured the difference).
Synchronous checkpoints, however, must always wait for all i/o to finish.
Take the contents of the callback functions and have them run in thread
context instead (aiodoned thread).  lfs_iocount no longer has to be
protected in splbio(), and quite a bit less of the segment construction
loop needs to be in splbio() as well.
If lfs_markv is handed a block that is not the correct size according to
the inode, refuse to process it.  (Formerly it was extended to the "correct"
size.)  This is possibly more prone to deadlock, but less prone to corruption.
lfs_segclean now outright refuses to clean segments that appear to have live
bytes in them.  Again this may be more prone to deadlock but avoids
corruption.
Replace ufsspec_close and ufsfifo_close with LFS equivalents; this means
that no UFS functions need to know about LFS_ITIMES any more.  Remove
the reference from ufs/inode.h.
Tested on i386, test-compiled on alpha.

Phase one of my three-phase plan to make LFS play nice with UBC, and bug-fixes
I found while making sure there weren't any new ones.

* Make the write clusters keep track of the buffers whose blocks they contain.
  This should make it possible to (1) write clusters using a page mapping
  instead of malloc, if desired, and (2) schedule blocks for rewriting
  (somewhere else) if a write error occurs.  Code is present to use
  pagemove() to construct the clusters but that is untested and will go away
  anyway in favor of page mapping.
* DEBUG now keeps a log of Ifile writes, so that any lingering instances of
  the "dirty bufs" problem can be properly debugged.
* Keep track of whether the Ifile has been dirtied by various routines that
  can be called by lfs_segwrite, and loop on that until it is clean, for
  a checkpoint.  Checkpoints need to be squeaky clean.
* Warn the user (once) if the Ifile grows larger than is reasonable for their
  buffer cache.  Both lfs_mountfs and lfs_unmount check since the Ifile can
  grow.
* If an inode is not found in a disk block, try rereading the block, under
  the assumption that the block was copied to a cluster and then freed.
* Protect WRITEINPROG() with splbio() to fix a hang in lfs_update.

Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

* add a VCLONED vnode flag that indicates a vnode representing a cloned
  device.
* rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass
  to VOP_REVOKE
* the revoke system call will revoke all aliases, as before, but not the
  clones
* vdevgone is called when detaching a device, so make it use REVOKECLONE
  to get rid of all clones as well
* clean up all uses of VOP_OPEN wrt. locking.
* add a few VOPS to spec_vnops that need to do something when it's a
  clone vnode (access and getattr)
* add a copy of the vnode vattr structure of the original 'master' vnode
  to the specinfo of a cloned vnode. could possibly redirect getattr to
  the 'master' vnode, but this has issues with revoke
* add a vdev_reassignvp function that disassociates a vnode from its
  original device, and reassociates it with the specified dev_t. to be
  used by cloning devices only, in case a new minor is allocated.
* change all direct references in drivers to v_devcookie and v_rdev
  to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes
  when debugging race conditions that still exist wrt. locking and
  revoking vnodes.
* make the locking state of a vnode consistent when passed to
  d_open and d_close (unlocked). locked would be better, but has
  some deadlock issues

Various changes to make cloning devices possible:

	* Add an extra argument (struct vnode **) to VOP_OPEN. If it is
	  not NULL, specfs will create a cloned (aliased) vnode during
	  the call, and return it there. The caller should release and
	  unlock the original vnode if a new vnode was returned. The
	  new vnode is returned locked.

	* Add a flag field to the cdevsw and bdevsw structures.
	  DF_CLONING indicates that it wants a new vnode for each
	  open (XXX is there a better way? devprop?)

	* If a device is cloning, always call the close entry
	  point for a VOP_CLOSE.


Also, rewrite cons.c to do the right thing with vnodes. Use VOPs
rather then direct device entry calls. Suggested by mycroft@

Light to moderate testing done an i386 system (arch doesn't matter
though, these are MI changes).

a whole bunch of changes to improve performance and robustness under load:

 - remove special treatment of pager_map mappings in pmaps.  this is
   required now, since I've removed the globals that expose the address range.
   pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
   no longer any need to special-case it.
 - eliminate struct uvm_vnode by moving its fields into struct vnode.
 - rewrite the pageout path.  the pager is now responsible for handling the
   high-level requests instead of only getting control after a bunch of work
   has already been done on its behalf.  this will allow us to UBCify LFS,
   which needs tighter control over its pages than other filesystems do.
   writing a page to disk no longer requires making it read-only, which
   allows us to write wired pages without causing all kinds of havoc.
 - use a new PG_PAGEOUT flag to indicate that a page should be freed
   on behalf of the pagedaemon when it's unlocked.  this flag is very similar
   to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
   pageout fails due to eg. an indirect-block buffer being locked.
   this allows us to remove the "version" field from struct vm_page,
   and together with shrinking "loan_count" from 32 bits to 16,
   struct vm_page is now 4 bytes smaller.
 - no longer use PG_RELEASED for swap-backed pages.  if the page is busy
   because it's being paged out, we can't release the swap slot to be
   reallocated until that write is complete, but unlike with vnodes we
   don't keep a count of in-progress writes so there's no good way to
   know when the write is done.  instead, when we need to free a busy
   swap-backed page, just sleep until we can get it busy ourselves.
 - implement a fast-path for extending writes which allows us to avoid
   zeroing new pages.  this substantially reduces cpu usage.
 - encapsulate the data used by the genfs code in a struct genfs_node,
   which must be the first element of the filesystem-specific vnode data
   for filesystems which use genfs_{get,put}pages().
 - eliminate many of the UVM pagerops, since they aren't needed anymore
   now that the pager "put" operation is a higher-level operation.
 - enhance the genfs code to allow NFS to use the genfs_{get,put}pages
   instead of a modified copy.
 - clean up struct vnode by removing all the fields that used to be used by
   the vfs_cluster.c code (which we don't use anymore with UBC).
 - remove kmem_object and mb_object since they were useless.
   instead of allocating pages to these objects, we now just allocate
   pages with no object.  such pages are mapped in the kernel until they
   are freed, so we can use the mapping to find the page to free it.
   this allows us to remove splvm() protection in several places.

The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

add a new VFS op, vfs_reinit, which is called when desiredvnodes is
adjusted via sysctl.  file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value.  the max number of FFS softdeps is also recalculated.

convert various file systems to use the <sys/queue.h> macros for
their hash tables.

Merge the short-lived perseant-lfsv2 branch into the trunk.

Kernels and tools understand both v1 and v2 filesystems; newfs_lfs
generates v2 by default.  Changes for the v2 layout include:

- Segments of non-PO2 size and arbitrary block offset, so these can be
  matched to convenient physical characteristics of the partition (e.g.,
  stripe or track size and offset).

- Address by fragment instead of by disk sector, paving the way for
  non-512-byte-sector devices.  In theory fragments can be as large
  as you like, though in reality they must be smaller than MAXBSIZE in size.

- Use serial number and filesystem identifier to ensure that roll-forward
  doesn't get old data and think it's new.  Roll-forward is enabled for
  v2 filesystems, though not for v1 filesystems by default.

- The inode free list is now a tailq, paving the way for undelete (undelete
  is not yet implemented, but can be without further non-backwards-compatible
  changes to disk structures).

- Inode atime information is kept in the Ifile, instead of on the inode;
  that is, the inode is never written *just* because atime was changed.
  Because of this the inodes remain near the file data on the disk, rather
  than wandering all over as the disk is read repeatedly.  This speeds up
  repeated reads by a small but noticeable amount.

Other changes of note include:

- The ifile written by newfs_lfs can now be of arbitrary length, it is no
  longer restricted to a single indirect block.

- Fixed an old bug where ctime was changed every time a vnode was created.
  I need to look more closely to make sure that the times are only updated
  during write(2) and friends, not after-the-fact during a segment write,
  and certainly not by the cleaner.

Change disk addressing unit to be the fragment, instead of the disk sector.
All quantities in the superblock, inodes, indirect blocks, etc. refer now
to this abstract unit (called "fsb" as it is in FFS) instead of disk sectors;
as a consequence segment summary blocks have to be multiples of a fragment in
size.  In v1 filesystems, compatibility code ensures that 1 fsb == 1 sector,
regardless of fragment size.

Fragments can now range in size between 512 and 32k; in the event that
LFS_LABELPAD (8k) is smaller than the disk address unit size, an extra
proto-superblock is kept at 8k from the beginning of the disk, to be used
*only* to locate the real superblocks.  (Not all of the userland knows about
this yet.)

Almost all of this was done not by me, but by joff.

Import of what I've been calling "LFSv2", that is, LFS with some features
added that require changes to the on-disk data structures.  These include:

- 64-bit time in everything but inodes
- User-specified segment offset, and segment size no longer
  restricted to PO2.
- Serial number on segment summaries in addition to timestamp, and
  a new volume identifier, to make roll-forward feasible without
  fear of finding old data and thinking it was new.

Although I think this version works at least as well as what's on the trunk,
we're not done yet; hence this commit is going in on a branch and not on
the trunk.  Enhancements that are not here yet include fragment addressing,
like FFS does, instead of block addressing.

Various bug-fixes to LFS, to wit:


Kernel:

* Add runtime quantity lfs_ravail, the number of disk-blocks reserved
  for writing.  Writes to the filesystem first reserve a maximum amount
  of blocks before their write is allowed to proceed; after the blocks
  are allocated the reserved total is reduced by a corresponding amount.

  If the lfs_reserve function cannot immediately reserve the requested
  number of blocks, the inode is unlocked, and the thread sleeps until
  the cleaner has made enough space available for the blocks to be
  reserved.  In this way large files can be written to the filesystem
  (or, smaller files can be written to a nearly-full but thoroughly
  clean filesystem) and the cleaner can still function properly.

* Remove explicit switching on dlfs_minfreeseg from the kernel code; it
  is now merely a fs-creation parameter used to compute dlfs_avail and
  dlfs_bfree (and used by fsck_lfs(8) to check their accuracy).  Its
  former role is better assumed by a properly computed dlfs_avail.

* Bounds-check inode numbers submitted through lfs_bmapv and lfs_markv.
  This prevents a panic, but, if the cleaner is feeding the filesystem
  the wrong data, you are still in a world of hurt.

* Cleanup: remove explicit references of DEV_BSIZE in favor of
  btodb()/dbtob().

lfs_cleanerd:

* Make -n mean "send N segments' blocks through a single call to
  lfs_markv".  Previously it had meant "clean N segments though N calls
  to lfs_markv, before looking again to see if more need to be cleaned".
  The new behavior gives better packing of direct data on disk with as
  little metadata as possible, largely alleviating the problem that the
  cleaner can consume more disk through inefficient use of metadata than
  it frees by moving dirty data away from clean "holes" to produce
  entirely clean segments.

* Make -b mean "read as many segments as necessary to write N segments
  of dirty data back to disk", rather than its former meaning of "read
  as many segments as necessary to free N segments worth of space".  The
  new meaning, combined with the new -n behavior described above,
  further aids in cleaning storage efficiency as entire segments can be
  written at once, using as few blocks as possible for segment summaries
  and inode blocks.

* Make the cleaner take note of segments which could not be cleaned due
  to error, and not attempt to clean them until they are entirely free
  of dirty blocks.  This prevents the case in which a cleanerd running
  with -n 1 and without -b (formerly the default) would spin trying
  repeatedly to clean a corrupt segment, while the remaining space
  filled and deadlocked the filesystem.

* Update the lfs_cleanerd manual page to describe all the options,
  including the changes mentioned here (in particular, the -b and -n
  flags were previously undocumented).

fsck_lfs:

* Check, and optionally fix, lfs_avail (to an exact figure) and
  lfs_bfree (within a margin of error) in pass 5.

newfs_lfs:

* Reduce the default dlfs_minfreeseg to 1/20 of the total segments.

* Add a warning if the sgs disklabel field is 16 (the default for FFS'
  cpg, but not usually desirable for LFS' sgs: 5--8 is a better range).

* Change the calculation of lfs_avail and lfs_bfree, corresponding to
  the kernel changes mentioned above.

mount_lfs:

* Add -N and -b options to pass corresponding -n and -b options to
  lfs_cleanerd.

* Default to calling lfs_cleanerd with "-b -n 4".


[All of these changes were largely tested in the 1.5 branch, with the
idea that they (along with previous un-pulled-up work) could be applied
to the branch while it was still in ALPHA2; however my test system has
experienced corruption on another filesystem (/dev/console has gone
missing :^), and, while I believe this unrelated to the LFS changes, I
cannot with good conscience request that the changes be pulled up.]

Clean up accounting of lfs_uinodes (dirty but unwritten inodes).

Make lfs_uinodes a signed quantity for debugging purposes, and set it to
zero as fs mount time.

Enclose setting/clearing of the dirty flags (IN_MODIFIED, IN_ACCESSED,
IN_CLEANING) in macros, and use those macros everywhere.  Make
LFS_ITIMES use these macros; updated the ITIMES macro in inode.h to know
about this.  Make ufs_getattr use ITIMES instead of FFS_ITIMES.

Allow the number of free segments reserved for the cleaner to be
parametrized in the filesystem, defaulting to MIN_FREE_SEGS = 2 but set
to something more reasonable at newfs_lfs time.

Note the number of blocks that have been scheduled for writing but which
are not yet on disk in an inode extension, i_lfs_effnblks.  Move
i_ffs_effnlink out of the ffs extension and onto the main inode, since
it's used all over the shared code and the lfs extension would clobber
it.

At inode write time, indirect blocks and inode-held blocks of inodes
that have i_lfs_effnblks != i_ffs_blocks are cleansed of UNWRITTEN disk
addresses, so that these never make it to disk.

Fixes associated with filling an LFS:

Change the space computation to appear to change the size of the *disk*
rather than the *bytes used* when more segment summaries and inode
blocks are written.  Try to estimate the amount of space that these will
take up when more files are written, so the disk size doesn't change too
much.

Regularize error returns from lfs_valloc, lfs_balloc, lfs_truncate: they
now fail entirely, rather than succeeding half-way and leaving the fs in
an inconsistent state.

Rewrite lfs_truncate, mostly stealing from ffs_truncate.  The old
lfs_truncate had difficulty truncating a large file to a non-zero size
(indirect blocks were not handled appropriately).

Unmark VDIROP on fvp after ufs_remove, ufs_rmdir, so these can be
reclaimed immediately: this vnode would not be written to disk again
anyway if the removal succeeded, and if it failed, no directory
operation occurred.

ufs_makeinode and ufs_mkdir now remove IN_ADIROP on error.

Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.

For each leaf filesystem, add appropriate vfs_done routine.

Changes to stabilize LFS.  The first two of these should also apply to the
1.4 branch.

* Use a separate per-fs lock, instead of ufs_hashlock, to protect the Inode
  free list.  This seems to prevent the "lockmgr: %d, not exclusive lock holder
  %d, unlocking" message I was mis-attributing last night to an unlocked vnode
  being passed to vrele.

* Change calling semantics of lfs_ifind, to give better error reporting:
  If fed a struct buf, it can report the block number of the offending inode
  block as well as the inode number.

* Back out rev 1.10 of lfs_subr.c, since the replacement code was slightly
  uglier while being functionally identical.

* Make lfs_vunref use the same free list convention as vrele/vput, so that
  vget does not remove vnodes from a hash list they are not on.

If ifile blocks were written before dirops were complete, and then the
system crashed, inodes could be allocated that were not referenced.  (Though
not a serious problem, it evidences itself in phase 4 of fsck_lfs.)  Fix
this by marking if_daddr with UNASSIGNED before the inodes are actually
written; at mount time the ifile is checked for UNASSIGNED entries and
any that are found are linked back into the free list.  (The latter
functionality should move into the roll-forward agent when it materializes.)

Give ufs_ihashget an extra argument: the flags passed to vget() for
locking. This way we can avoid locking against ourselves when
ufs_ihashget is called during the flushing of metadata. XXX

Also, comment out a VOP_FSYNC call that I think is now unneeded, and
put a diagnostic printf there to check if this still happens.

Make changes that will allow an LFS filesystem to be used as the root
filesystem.  In particular,

- Fix mknod deadlock, described in PR 8172.
- Enable lfs_mountroot.
- Make lfs_writevnodes treat filesystems mounted on lfs device nodes properly,
  by flushing that device rather than trying to add blocks to the device inode.

This, in combination with lfs boot blocks, will allow operation of an all-lfs
system.

Rudimentary support for LFS under UBC:

- LFS-specific VOP_BALLOC and VOP_PUTPAGES vnode ops.

- getblk VREG panic #ifdef'd out (can be reinstated when Ifile is
  internalized and Ifile can be made another type from VREG)

- interface to VOP_PUTPAGES changed to pass all pager flags, not
  just sync.  FS putpages routines must know about the pager flags.

- new LFS magic disk address, -2 ("unwritten"), meaning accounted for
  but not assigned to a fixed disk location (since LFS does these two
  things separately, and the previous accounting method using buffer
  headers no longer will work).  Changed references to (foo == (daddr_t)-1)
  to (foo < 0).  Since disk drivers reject all addresses < 0, this should
  not present a problem for other FSs.

Fixed lfs_update (and related functions) so that calls from lfs_fsync
will DTRT with vnodes marked VDIROP.  In particular, the message
"flushing VDIROP" will no longer appear, and the filesystem will remain
stable in the event of a crash.

This was particularly a problem with NFS-exported LFSes, since fsync
was called on every file close.

Pull-up of changes made to the trunk on Sunday [1.30->1.32], to wit:

Take out the `#ifdef USE_UFSHASH'; use ufs_hashlock to lock the inode free
list instead of free_lock.

Fix inode reporting in lfs_statfs (the meaning of f_files and f_ffree was
reversed).

Fix "lfs_ifind: dinode xxx not found" panic.  When inodes were freed, then
immediately reloaded, their dinodes were located in an inode block which
was not on disk at the advertized location, nor in the cache (although it
would be flushed to disk next segment write).  Fix this by using getblk()
instead of lfs_newbuf() for inode blocks.

Better checking for held inode locks in lfs_fastvget, for a number of
error conditions.  Also change the default setting of lfs_clean_vnhead to
0, which seems to make the locking problems go away (although this is
difficult to test as I can't reliably reproduce them).

Make sure that the wakeup occurs for vnodes that lfs_update might be
sleeping on (nodes which are not marked IN_MODIFIED/IN_CLEANING, but which
have dirty buffers), by marking them with the appropriate flag if
dirtybuffers were added while the write was in progress.

Fix block counting during file truncation, if not truncating to zero.

Disallow threshold-initiated cache flush when dirops are active.  Also,
make SET_ENDOP use lfs_check instead of inlining most of it.

Improve the debugging printfs in the cleaner syscalls (in particular, make
it obvious that they're coming from lfs).

Check the superblock version field, and refuse to mount the filesystem if
the version number is higher than we know about.  This allows, e.g.,
changes in the format of the ifile, segment size restrictions and
boundaries, etc., which would not affect existing fields in the
superblock, but which would drastically affect the filesystem, to be
smoothly integrated at a later date.

Mark the current segment with SEGUSE_ACTIVE at mount time, rather than waiting
for the first write.  If this is not done, the cleaner may try to clean the
current segment out from under the writer if the filesystem is mounted after
a crash (or any other time that the dirty:clean segment ration is high enough).

* Make sure the whole ufsmount is zeroed, as the export code relies on this.
* If we decided to use the second/alternate superblock, make sure to copy the
  in-core version from the right buffer.
Also, reenable NFS exporting.

New sources should leave the LFS in a more-or-less working state.  Changes
include:

	- DIROP segregation is enabled, and greater care is taken
	  to make sure that a checkpoint completes.  Fsck is not
	  needed to remount the filesystem.
	- Several checks to make sure that the LFS subsystem does not
	  overuse various resources (memory, in particular).
	- The cleaner routines, lfs_markv in particular, are completely
	  rewritten.  A buffer overflow is removed.  Greater care is taken
	  to ensure that inodes come from where lfs_cleanerd say they come
	  from (so we know nothing has changed since lfs_bmapv was called).
	- Fragment allocation is fixed, so that writes beyond end-of-file
	  do the right thing.

Add support for reading/writing FFS in non-native byte order, conditioned
to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped
when used (as they are acceeded directly in the buffer cache).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.

Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h:
- added an "union inode_ext" to struct inode, for the per-fs extentions.
  For now only ext2fs uses it.
- i_din is now an union:
	union {
		struct  dinode ffs_din; /* 128 bytes of the on-disk dinode. */
		struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
	} i_din
  Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
  macro, depending on the time of the inode. ITIMES is used where necessary,
  FFS_ITIMES and EXT2FS_ITIMES in other places.
