Subject: [GIT PULL] xfs: bug fixes for 5.14-rc4

Hi Linus,

Please pull this branch containing a bunch of bug fixes in XFS.  Dave
and I have been busy the last couple of weeks to find and fix as many
log recovery bugs as we can find; here are the results so far.  Go
fstests -g recoveryloop! ;)

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.

  xfs: prevent spoofing of rtbitmap blocks when recovering buffers (2021-07-29 09:27:29 -0700)

----------------------------------------------------------------
Fixes for 5.14-rc4:
 * Fix a number of coordination bugs relating to cache flushes for
   metadata writeback, cache flushes for multi-buffer log writes, and
   FUA writes for single-buffer log writes.
 * Fix a bug with incorrect replay of attr3 blocks.
 * Fix unnecessary stalls when flushing logs to disk.
 * Fix spoofing problems when recovering realtime bitmap blocks.

Dave Chinner (11):
      xfs: flush data dev on external log write
      xfs: external logs need to flush data device
      xfs: fold __xlog_state_release_iclog into xlog_state_release_iclog
      xfs: fix ordering violation between cache flushes and tail updates
      xfs: factor out forced iclog flushes
      xfs: log forces imply data device cache flushes
      xfs: avoid unnecessary waits in xfs_log_force_lsn()
      xfs: logging the on disk inode LSN can make it go backwards
      xfs: Enforce attr3 buffer recovery order
      xfs: need to see iclog flags in tracing
      xfs: limit iclog tail updates
