Subject: [GIT PULL] xfs: fixes for v4.20-rc4

Hi Linus,

Dave and I have continued our work fixing corruption problems that can
be found when running long-term burn-in exercisers on xfs.  Here are
some patches fixing most of the problems, but there will likely be more.
:/

Anyhow, this series merges cleanly with master as of last night, so
please let me know if you encounter problems.
