[GIT PULL] xfs: fixes for 5.3-rc6

[Darrick J. Wong]

Hi Linus,

Here are a few more bug fixes that trickled in since the last pull.
They've survived the usual xfstests runs and merge cleanly with this
morning's master.  Please let me know if anything strange happens.

I expect there to be one more pull request tomorrow for the fix to that
quota related inode unlock bug that we were reviewing last night, but it
will continue to soak in the testing machine for several more hours.

--D
