- Try to keep snapshot indirect blocks contiguous.  This speeds up snapshot
  creation by a factor of ~3 and reduces the file system suspension time by
  a factor of ~5.

- Refine the scope of WAPBL transactions and the limit for deallocations in
  one transaction so we should no longer get a "wapbl_flush: current
  transaction too big to flush" panic when creating or removing snapshots
  on larger logging disks.

- fss(4): Allow FSSIOCSET to set the initial flags.  Add a new flag
  "FSS_UNLINK_ON_CREATE" to unlink the backing store before the snapshot
  gets created.  With this change dump(8) no longer dumps the zero-sized,
  but named snapshot it is working on.

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.

Set the limit for deallocations in one transaction to a more realistic
(and much lower) value.  When flushing the log these deallocations will
produce new blocks and that may execeed the journal size resulting in
a "wapbl_flush: current transaction too big to flush" panic.
Seen when removing a large snapshot.

mnt_fs_bshift is the filesystem block size, not the fragment size.

Revert to physical block size. This is fine as long as filesystem

Use correct offset to block number calculations.

Also change access to filesystem blocks to be done by fragment instead
of by physical block. Fragments are the fundamental blocks of the
filesystem.

For a theoretical filesystem that accesses the disk in smaller units
than stored in mp->mnt_fs_bshift, the assumption might be wrong. But
this will also break other subsystems. The value mp->mnt_dev_bshift
which formerly represents the physical sector size is currently only
virtual in NetBSD (always DEV_BSIZE).

- A fix for an issue that can lead to "ffs_valloc: dup" due to dirty cg
  buffers being invalidated. Problem discovered and patch by dholland@.
- If the syncer fails to lazily sync a vnode due to lock contention,
  retry 1 second later instead of 30 seconds later.
- Flush inode atime updates every ~10 seconds (this makes most sense with
  logging). Presently they didn't hit the disk for read-only files or
  devices until the file system was unmounted. It would be better to trickle
  the updates out but that would require more extensive changes.
- Fix issues with file system corruption, busy looping and other nasty
  problems when logging and non-logging file systems are intermixed,
  with one being the root file system.
- For logging, do not flush metadata on an inode-at-a-time basis if the sync
  has been requested by ioflush. Previously, we could try hundreds of log
  sync operations a second due to inode update activity, causing the syncer
  to fall behind and metadata updates to be serialized across the entire
  file system. Instead, burst out metadata and log flushes at a minimum
  interval of every 10 seconds on an active file system (happens more often
  if the log becomes full). Note this does not change the operation of
  fsync() etc.
- With the flush issue fixed, re-enable concurrent metadata updates in
  vfs_wapbl.c.

Turn on WAPBL_DEBUG_SERIALIZE in order to use RW_WRITER locks instead
of RW_READER locks in wapbl_begin().  Include the following comment as
well:

	XXX: The original code calls for the use of a RW_READER lock
	here, but it turns out there are performance issues with high
	metadata-rate workloads (e.g. multiple simultaneous tar
	extractions).  For now, we force the lock to be RW_WRITER,
	since that currently has the best performance characteristics
	(even for a single tar-file extraction).
