Pull xfs updates from Darrick Wong:
 "There's a lot in this cycle.

  Starting with bug fixes: To avoid livelocks between the logging code
  and the quota code, we've disabled the ability of quotaoff to turn off
  quota accounting. (Admins can still disable quota enforcement, but
  truly turning off accounting requires a remount.) We've tried to do
  this in a careful enough way that there shouldn't be any user visible
  effects aside from quotaoff no longer randomly hanging the system.

  We've also fixed some bugs in runtime log behavior that could trip up
  log recovery if (otherwise unrelated) transactions manage to start and
  commit concurrently; some bugs in the GETFSMAP ioctl where we would
  incorrectly restrict the range of records output if the two xfs
  devices are of different sizes; a bug that resulted in fallocate
  funshare failing unnecessarily; and broken behavior in the xfs inode
  cache when DONTCACHE is in play.

  As for new features: we now batch inode inactivations in percpu
  background threads, which sharply decreases frontend thread wait time
  when performing file deletions and should improve overall directory
  tree deletion times. This eliminates both the problem where closing an
  unlinked file (especially on a frozen fs) can stall for a long time,
  and should also ease complaints about direct reclaim bogging down on
  unlinked file cleanup.

  Starting with this release, we've enabled pipelining of the XFS log.
  On workloads with high rates of metadata updates to different shards
  of the filesystem, multiple threads can be used to format committed
  log updates into log checkpoints.

  Lastly, with this release, two new features have graduated to
  supported status: inode btree counters (for faster mounts), and
  support for dates beyond Y2038. Expect these to be enabled by default
  in a future release of xfsprogs.

  Summary:

   - Fix a potential log livelock on busy filesystems when there's so
     much work going on that we can't finish a quotaoff before filling
     up the log by removing the ability to disable quota accounting.

   - Introduce the ability to use per-CPU data structures in XFS so that
     we can do a better job of maintaining CPU locality for certain
     operations.

   - Defer inode inactivation work to per-CPU lists, which will help us
     batch that processing. Deletions of large sparse files will
     *appear* to run faster, but all that means is that we've moved the
     work to the backend.

   - Drop the EXPERIMENTAL warnings from the y2038+ support and the
     inode btree counters, since it's been nearly a year and no
     complaints have come in.

   - Remove more of our bespoke kmem* variants in favor of using the
     standard Linux calls.

   - Prepare for the addition of log incompat features in upcoming
     cycles by actually adding code to support this.

   - Small cleanups of the xattr code in preparation for landing support
     for full logging of extended attribute updates in a future cycle.

   - Replace the various log shutdown state and flag code all over xfs
     with a single atomic bit flag.

   - Fix a serious log recovery bug where log item replay can be skipped
     based on the start lsn of a transaction even though the transaction
     commit lsn is the key data point for that by enforcing start lsns
     to appear in the log in the same order as commit lsns.

   - Enable pipelining in the code that pushes log items to disk.

   - Drop ->writepage.

   - Fix some bugs in GETFSMAP where the last fsmap record reported for
     a device could extend beyond the end of the device, and a separate
     bug where query keys for one device could be applied to another.

   - Don't let GETFSMAP query functions edit their input parameters.

   - Small cleanups to the scrub code's handling of perag structures.

   - Small cleanups to the incore inode tree walk code.

   - Constify btree function parameters that aren't changed, so that
     there will never again be confusion about range query functions
     changing their input parameters.

   - Standardize the format and names of tracepoint data attributes.

   - Clean up all the mount state and feature flags to use wrapped
     bitset functions instead of inconsistently open-coded flag checks.

   - Fix some confusion between xfs_buf hash table key variable vs.
     block number.

   - Fix a mis-interaction with iomap where we reported shared delalloc
     cow fork extents to iomap, which would cause the iomap unshare
     operation to return IO errors unnecessarily.

   - Fix DONTCACHE behavior"
