Rename ambiguous macros:
   MAXDIRSIZE -> UFS_MAXDIRSIZE or LFS_MAXDIRSIZE
   NINDIR -> FFS_NINDIR, EXT2_NINDIR, LFS_NINDIR, or MFS_NINDIR
   INOPB -> FFS_INOPB, LFS_INOPB
   INOPF -> FFS_INOPF, LFS_INOPF
   blksize -> ffs_blksize, ext2_blksize, or lfs_blksize
   sblksize -> ffs_blksize

These are not the only ambiguously defined filesystem macros, of
course, there's a pile more. I may not have found all the ambiguous
definitions of blksize(), too, as there are a lot of other things
called 'blksize' in the system.

Add an accessor -- ufs_maxphys() -- to check the maximum transfer size
for a given UFS mountpoint, and move the code from mount that finds
the underlying disk and resets the mountpoint max transfer size into a
utility function, ufs_update_maxphys().

Add a global serial number that counts disk property changes to which
filesystems are meant to accomodate themselves.  Make ufs_maxphys()
check it.  This is a sort of flag-polling interface that avoids callbacks
into the filesystem code, but will require freezing filesystems and
draining in-flight transactions before a decrease in size that is
mandatory (like attaching a disk with a smaller maximum transfer size
as a spare in a RAIDframe set), rather than "advisory", like finding
out set geometry from a RAID controller long after boot and deciding
a smaller transfer size would be optimal, can be signalled.  Still, the
"advisory" case is the common one so this is progress.

Make a bit of an example of RAIDframe by making it bump this new
serial number when disks are added to the subsystem.  I will attack
one of the hardware RAID drivers (probably arcmsr) next.

Stuff UFS_ in front of a few of ufs's symbols to reduce namespace
pollution. Specifically:
   ROOTINO -> UFS_ROOTINO
   WINO -> UFS_WINO
   NXADDR -> UFS_NXADDR
   NDADDR -> UFS_NDADDR
   NIADDR -> UFS_NIADDR
   MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
   MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.

No functional change intended.

In the FFS writebehind code (ufs_readwrite.c:WRITE()), use division
and multiplication instead of shifts, to accomodate devices with
MAXPHYS that is a multiple of the page size, but not a power of 2.

MegaRAID neatly writes out 192k chunks now.

An open question: is is really a good idea to always writebehind
at the largest size supported by the device?  Likely not, as this
could have a major impact on I/O fairness.  OS X and Solaris both
seem to limit transfers to 128k likely for this reason (the same
problem exists with the readahead code but since it is adaptive,
it will not *always* do huge transfers).

However, simply imposing a smallish limit like 128k here seems
like a bad idea because then we cannot accomodate greedy devices
like RAID, for which you want something like 128k * number of
data components.  Hmmmmmm.

* 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.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
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
basis. mount_mfs(8) can also turn quotas on.

Add a new inode flag, SF_SNAPINVAL, to be set on SF_SNAPSHOT inodes when
the snapshot is invalid.
Set SF_SNAPSHOT | SF_SNAPINVAL early when initializing a snapshot indode,
so that quota are bypassed for allocations on this inode.
Set SF_SNAPSHOT | SF_SNAPINVAL (instead of clearing SF_SNAPSHOT) when
expuge()ing a snapshot inode, so that userland tools working on the
snapshot (e.g. fsck or dump) can properly handle this inode.

The main point at this time is to have fsck_ffs -X properly compute quotas;
as a bonus persistent snapshots files won't show up in a dump(8) from a
snapshot.

This may also help speeding up taking snapshots, by bypassing expuge()
for snapshot inodes completely (but this needs more thoughs).


Briefly discussed with hannken@ in private mail.

Enforce RLIMIT_FSIZE before VOP_WRITE.  This adds support to file
system drivers where it was missing from and fixes one buggy
implementation.  The arguably weird semantics of the check are
maintained (v_size vs. va_bytes, overwrite).

Add snapshot support for logging ffs file systems.

- Add UFS_WAPBL_BEGIN() / UFS_WAPBL_END() where needed.

- Expunge WAPBL log inodes from snapshots.

- Ffs_copyonwrite() and ffs_snapblkfree() must run inside a WAPBL transaction.

- Add ffs_gop_write() as a wrapper around genfs_gop_write() that makes sure
  genfs_gop_write() gets always called inside a WAPBL transaction.

Deny read/write access to snapshot vnodes.  We use fss(4) to read from
snapshots.  With this policy in place:

- Separate the snapshot vnode lock from the snapshot common lock.
  Snapshots no longer need recursive vnode locks.

- Use a mutex (si_snaplock) to serialize creation, deletion, reading and
  writing of snapshots.

- Move ffs_read() for snapshots into ffs_snapshot.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.

Network protocol interrupts can now block on locks, so merge the globals
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

- Increase the number of thread priorities from 128 to 256. How the space
  is set up is to be revisited.
- Implement soft interrupts as kernel threads. A generic implementation
  is provided, with hooks for fast-path MD code that can run the interrupt
  threads over the top of other threads executing in the kernel.
- Split vnode::v_flag into three fields, depending on how the flag is
  locked (by the interlock, by the vnode lock, by the file system).
- Miscellaneous locking fixes and improvements.

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).

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().

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

adjust the UBC mapping code to support non-vnode uvm_objects.
this means we can no longer look at the vnode size to determine how many
pages to request in a fault, which is good since for NFS the size can change
out from under us on the server anyway.  there's also a new flag UBC_UNMAP
for ubc_release(), so that the file system code can make the decision about
whether to cache mappings for files being used as executables.

Fixing age old cruft:
* Rather than using mnt_maxsymlinklen to indicate that a file systems returns

Add 3 new elements to ufsmount:
* um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed
  in the first place).
* um_dirblksiz, which tracks the current directory block size, eliminating the
  FS-specific checks littered throughout the code.  This may be used later to
  make the block size variable.
* um_maxfilesize, which is the maximum file size, possibly adjusted lower due
  to implementation issues.

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through

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.

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.

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.

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.]

Prevent dirops from getting around lfs_check and wedging the buffer cache.
All the dirop vnops now mark the inodes with a new flag, IN_ADIROP, which
is removed as soon as the dirop is done (as opposed to VDIROP which stays
until the file is written).  To address one issue raised in PR#9357.

Change the sementics of the last parameter from a boolean ("waitfor") to
a set of flags ("flags").  Two flags are defined, UPDATE_WAIT and
UPDATE_DIROP.

Under the old semantics, VOP_UPDATE would block if waitfor were set,
under the assumption that directory operations should be done
synchronously.  At least LFS and FFS+softdep do not make this
assumption; FFS+softdep got around the problem by enclosing all relevant
calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply
ignored waitfor, one of the reasons why NFS-serving an LFS filesystem
did not work properly.

Under the new semantics, the UPDATE_DIROP flag is a hint to the
fs-specific update routine that the call comes from a dirop routine, and
should be wait for, or not, accordingly.

Closes PR#8996.

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.

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

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.

* Make 2nd and 3rd args timespecs, not timevals.
* Consistently pass a Boolean as the 4th arg (except in LFS).
Also, fix ffs_update() and lfs_update() to actually change the nsec fields.

avoid unnecessary aging of buffers.  This used to make sense, when buffer
caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow.  Suggested by Bob Baron.

new prototypes and picky compilers make a volatile mess.
