[GIT PULL] xfs: fixes for 5.5-rc3

[Darrick J. Wong]

Hi Linus,

Please pull these bug fixes for 5.5-rc3, which fix a few bugs that could
lead to corrupt files, fsck complaints, and filesystem crashes.

The branch has survived a couple of days of xfstests runs and merges
cleanly with this morning's master.  Please let me know if anything
strange happens.

  xfs: Make the symbol 'xfs_rtalloc_log_count' static (2019-12-20 08:07:31 -0800)

----------------------------------------------------------------
Fixes for 5.5:
- Minor documentation fixes
- Fix a file corruption due to read racing with an insert range
operation.
- Fix log reservation overflows when allocating large rt extents
- Fix a buffer log item flags check
- Don't allow administrators to mount with sunit= options that will
cause later xfs_repair complaints about the root directory being
suspicious because the fs geometry appeared inconsistent
- Fix a non-static helper that should have been static
