[GIT PULL] xfs: fixes for 5.17-rc3

[Darrick J. Wong]

Hi Linus,

Please pull this branch containing bug fixes for XFS for 5.17-rc3.
I was auditing operations in XFS that clear file privileges, and
realized that XFS' fallocate implementation drops suid/sgid but doesn't
clear file capabilities the same way that file writes and reflink do.
There are VFS helpers that do it correctly, so refactor XFS to use them.
I also noticed that we weren't flushing the log at the correct point in
the fallocate operation, so that's fixed too.

As usual, I did a test-merge with upstream master as of a few minutes
ago, and didn't see any conflicts.  Please let me know if you encounter
any problems.

  xfs: ensure log flush at the end of a synchronous fallocate call (2022-02-01 14:14:48 -0800)

----------------------------------------------------------------
Fixes for 5.17-rc3:
 - Fix fallocate so that it drops all file privileges when files are
   modified instead of open-coding that incompletely.
 - Fix fallocate to flush the log if the caller wanted synchronous file
   updates.
