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.

UVM locking changes, proposed on tech-kern:

- Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock.
- Break v_interlock and vmobjlock apart.  v_interlock remains a mutex.
- Do partial PV list locking in the x86 pmap.  Others to follow later.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

Fix catastrophic bug in lfs_rewind() that changed segment numbers
(lfs_curseg/lfs_nextseg in the superblock) using the wrong units.
These fields are for whatever reason the start addresses of segments

This only apparently affects dumping from a mounted fs; however, it
trashes the fs.
I would really, really like to have a static analysis tool that can
keep track of the units things are measured in, since fs code is full
of conversion macros and the macros are named inscrutable things like
"sntod" whose letters don't necessarily even correspond to the units
they convert. It is surprising that more of these are not wrong.

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.

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.

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

More lfs superblock accessors.
(This changes the rest of the code over; all the accessors were
already added.)

The difference between this commit and the previous one is arbitrary,
but the previous one passed the regression tests on its own so I'm
keeping it separate to help with any bisections that might be needed
in the future.

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.

- 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.

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

* 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.

Three changes in a single commit.

- drop the notion of frags (LFS fragments) vs fsb (FFS fragments)
  The code uses a complicated unity function that just makes the
  code difficult to understand.

- support larger sector sizes. Fix disk address computations
  to use DEV_BSIZE in the kernel as required by device drivers
  and to use sector sizes in userland.

- Fix several locking bugs in lfs_bio.c and lfs_subr.c.

Make sure all cached buffers with valid, not yet written data have been
run through copy-on-write.  Call fscow_run() with valid data where possible.

The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against
endless recursion.

- Add a flag B_MODIFY to bread(), breada() and breadn().  If set the caller
  intends to modify the buffer returned.

- Always run copy-on-write on buffers returned from ffs_balloc().

- Add new function ffs_getblk() that gets a buffer, assigns a new blkno,
  may clear the buffer and runs copy-on-write.  Process possible errors
  from getblk() or fscow_run().  Part of PR kern/38664.

Instead of having lfs muck directly about with vnode free lists,
introduce vrele2(), which allows to release vnodes the way lfs
sometimes wants it:
  + without calling inactive
  + inserting the vnode at the head of the freelist (this is a very
    questionable optimization that isn't even enabled by default,
    but I went along with the same semantics for now)

Implementation of per-CPU work-queues support for workqueue(9) interface.
WQ_PERCPU flag for workqueue and additional argument for workqueue_enqueue()
to assign a CPU might be used. Notes:
 - For now, the list is used for workqueue_queue, which is non-optimal,
   and will be changed with array, where index would be CPU ID.
 - The data structures should be changed to be cache-friendly.

Using POOL_INIT here makes no sense, since file systems always have
an init method.  So get rid of it and #ifdef _LKM and just always
init in the init method.  Give malloc types the same treatment.
Makes file systems nicer to work with in linksetless environments
and fixes a few LKM discrepancies.

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.

Replace the LIST structure mp->mnt_vnodelist to a TAILQ structure since all
vnodes were synced and processed backwards. This meant that the last
accessed node was processed first and the earlierst last.

An extra benefit is the removal of the ugly hack from the Berkly days on

In the proces, i've also replaced the various variations hand written loops
by the TAILQ_FOREACH() macro's.

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.

Change LFCNWRAP{STOP,GO} to make them more suitable for snapshotting; in
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again.  Updated the ckckp
regression test to use the new semantics.

dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4).  Fixed a couple
other problems with dump_lfs that manifested themselves during testing.

fix a simonb-timecounters regression.
the precision of getnanotime() is not suitable for file timestamps.
esp. when it's nfs-exported.

- introduce vfs_timestamp().
  (the name is from freebsd.  currently merely a wrapper of nanotime())
- for ufs-like filesystems, use it rather than getnanotime().

XXX check other filesystems.

Fixes to address the "vinvalbuf: dirty blocks" panic that can occur when
many inodes are cleaned at once.  Make sure that we write all the pages
on vnodes that are being flushed, even if we don't think there's room;
drain v_numoutput before lfs_vflush() completes.

that a large number of inodes are fed to lfs_markv() all at once.

More correctly reconstruct the on-disk state at every checkpoint, rather
than relying on the entire state at the point of wrapping to be accurate
(that is only true the first time we wrap).  Add a "make abort" target to
make rerunning the test more convenient when it has failed and we're done

Introduce two fcntl calls that freeze the filesystem right at the point
where segment 0 is being considered for writing.  This allows for automated
checkpoint vailidity scanning, and could be used (in conjunction with the
existing LFCNREWIND) for e.g. snapshot dumps as well.
Include a regression test that does such scanning.
When writing the Ifile, loop through the dirty block list three times to
make sure that the checkpoint is always consistent (the first and second
times the Ifile blocks can cross a segment boundary; not so the third time
unless the segments are very small).  Discovered by using the aforementioned
regression test.

* Raise priority of LFCNSEGWAIT to PVFS; PUSER is way too low for
   something the pagedaemon is relying on.

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).

Introduce two fcntl calls that freeze the filesystem right at the point
where segment 0 is being considered for writing.  This allows for automated
checkpoint vailidity scanning, and could be used (in conjunction with the
existing LFCNREWIND) for e.g. snapshot dumps as well.

Include a regression test that does such scanning.

When writing the Ifile, loop through the dirty block list three times to
make sure that the checkpoint is always consistent (the first and second
times the Ifile blocks can cross a segment boundary; not so the third time
unless the segments are very small).  Discovered by using the aforementioned
regression test.

Make lfs_vref/lfs_vunref not need to know about VXLOCK and VFREEING
explicitly (especially since we didn't know about VFREEING at all before),
but notice the EBUSY return from vget() instead.

Fix some more MP locking protocol issues, most of which were pointed out by
Christian Ehrhardt this morning on tech-kern.

Several minor bug fixes:

* Correct (weak) segment lock assertions in lfs_fragextend and lfs_putpages.
* Keep IN_MODIFIED set if we run out of avail in lfs_putpages.
* Don't try to (re)write buffers on a VBLK vnode; fixes a panic I found
  while running with an LFS root.
* Raise priority of LFCNSEGWAIT to PVFS; PUSER is way too low for
  something the pagedaemon is relying on.

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).

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".

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.

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.

The checkpoint loop always used (multiples of) lfs_sepb as the number
of segments to mark. However, this may be much more than lfs_nseg.

Originally this wasn't a big problem, since only the structures in the
diskblock were changed, but nowadays there's a mirror of the segflags
in the in-core superblock. This problem caused the code to walk
way past the end of that allocated area, causing memory corruption
in other kernel structures. So, use lfs_nseg as the maximum, as it should be.

While here, simplify the loop; it had become an obfuscated piece of
code overtime.

Fix a buffer overflow bug in the LFS_UBC case that manifested itself
either as a mysterious UVM error or as "panic: dirty bufs".  Verify
maximum size in lfs_malloc.

Teach lfs_updatemeta and lfs_shellsort about oversized cluster blocks from
lfs_gop_write.

When unwiring pages in lfs_gop_write, deactivate them, under the theory

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.

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" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)

Pull up revision 1.79 (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.

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

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.

Correct accounting of lfs_avail, locked_queue_count, and locked_queue_bytes.
(PR #11468).  In the case of fragment allocation, check to see if enough
space is available before extending a fragment already scheduled for writing.

The locked_queue_* variables indicate the number of buffer headers and bytes,
respectively, that are unavailable to getnewbuf() because they are locked up
waiting for LFS to flush them; make sure that that is actually what we're
counting, i.e., never count malloced buffers, and always use b_bufsize instead
of b_bcount.

If DEBUG is defined, the periodic calls to lfs_countlocked will now complain
if either counter is incorrect.  (In the future lfs_countlocked will not need
to be called at all if DEBUG is not defined.)

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.]

Fix errors observed while trying to fill the filesystem with yesterday's
fixes:

- Write copies of bfree and avail in the CLEANERINFO block, so the

- Tighten up accounting of lfs_avail (more needs to be done).

- When cleansing indirect blocks of UNWRITTEN, make sure not to mark

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.

Change the way LFS does block accounting, from trying to infer from the
buffer cache flags, to marking the inode and/or indirect blocks with a
special disk address UNWRITTEN==-2 when a block is accounted for.  (This
address is never written to disk, but only used in-core.  This is essentially
the same method of block accounting as on the UBC branch, where the buffer
headers don't exist.)  Make sure that truncation is handled properly,
especially in the case of holey files.

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

* 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.)

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.

overcount for inodes, and don't count segment summaries.  Thus, for empty

Pull-up of changes made to the trunk on Sunday [1.23->1.26], 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.

lfs_truncate calls vinvalbuf to invalidate all currently-hald buffers, which
in turn forces a flush of the vnode, whether or not it is involved in a dirop.
(This can happen during a remove or rmdir, when the directory is shrunk.)
Because of the nature of dirops, however, flushing a vnode involved in a dirop
is disallowed (and was marked with a panic).  This patch has lfs_truncate
call a specialized vinvalbuf that only invalidates buffers following the new
end-of-file, and thus does not require a flush.  Also the panic is demoted,
in case I missed any other path to lfs_vflush.

Make sysctl variable lfs_clean_vnhead do what it was supposed to do,
namely, toggle whether vnodes loaded only for cleaning (as opposed to
normal filesystem use) are freed to the *head* of the vnode free list,
rather than the tail.  This should avoid a possible cache flushing
effect, if the cleaner cleans a segment containing a large number of
live inodes.

Fixes to make dirops and lfs_vflush play together well.  In particular,
if we are short on vnodes, lfs_vflush from another process can grab a
vnode that lfs_markv has already processed but not yet written; but
lfs_markv holds the seglock.  When lfs_vflush gets around to writing it,
the context for copyin is gone.  So, now lfs_markv calls copyin itself,
rather than having lfs_writeseg do it.

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 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.
