[GIT PULL] xfs: bug fixes for 5.1-rc3

[Darrick J. Wong]

Hi Linus,

Here are a few fixes for some corruption bugs and uninitialized variable
problems.  The few patches here have gone through a few days worth of
fstest runs with no new problems observed; and they merge cleanly with
master as of a few hours ago.  Please let me know if you encounter any
problems merging them.
