[GIT PULL] xfs: moar new code for 5.6

[Darrick J. Wong]

Hi Linus,

Please pull this second batch of new changes for 5.6-rc1.  This contains
the buffer error code refactoring I mentioned last week, now that it has
had extra time to complete the full xfs fuzz testing suite to make sure
there aren't any obvious new bugs.

This merges cleanly against upstream as of about 15 minutes ago.  Note
that the -merge-7 and -merge-8 tags both point to the same ten day old
commit; the message attached to -8 reflects only the changes since last
week's pull.  Please let me know if anything odd happens during the
merge, though it should be clean.

  xfs: fix xfs_buf_ioerror_alert location reporting (2020-01-26 14:32:27 -0800)

----------------------------------------------------------------
(More) new code for 5.6:
- Refactor the metadata buffer functions to return the usual int error
value instead of the open coded error checking mess we have now.
