Subject: [GIT PULL] xfs: new code for 5.17

Hi Linus,

Please pull this new code for Linux 5.17.  The big new feature here is
that the mount code now only bothers to try to free stale COW staging
extents if the fs unmounted uncleanly.  This should reduce mount times,
particularly on filesystems supporting reflink and containing a large
number of allocation groups.

Everything else this cycle are bugfixes, as the iomap folios conversion
should be plenty enough excitement for anyone.  That and I ran out of
brain bandwidth after Thanksgiving last year.

The branch merges cleanly against upstream as of a few minutes ago.
Please let me know if anything else strange happens during the merge
process.  There will definitely be a second pull request coming with
at least one more bug fix and most probably a full withdrawal of the
recently troublesome ALLOCSP ioctl family.

  xfs: warn about inodes with project id of -1 (2022-01-06 10:43:30 -0800)

----------------------------------------------------------------
New code for 5.17:
 - Fix log recovery with da btree buffers when metauuid is in use.
 - Fix type coercion problems in xattr buffer size validation.
 - Fix a bug in online scrub dir leaf bestcount checking.
 - Only run COW recovery when recovering the log.
 - Fix symlink target buffer UAF problems and symlink locking problems
   by not exposing xfs innards to the VFS.
 - Fix incorrect quotaoff lock usage.
 - Don't let transactions cancel cleanly if they have deferred work
   items attached.
 - Fix a UAF when we're deciding if we need to relog an intent item.
 - Reduce kvmalloc overhead for log shadow buffers.
 - Clean up sysfs attr group usage.
 - Fix a bug where scrub's bmap/rmap checking could race with a quota
   file block allocation due to insufficient locking.
 - Teach scrub to complain about invalid project ids.
