[GIT PULL] xfs: bug fixes for 5.7-rc1

[Darrick J. Wong]

Hi Linus,

Please pull this handful of fixes for 5.7.  The three commits here fix
some livelocks and other clashes with fsfreeze, a potential corruption
problem, and a minor race between processes freeing and allocating space
when the filesystem is near ENOSPC.

This branch merges cleanly with master as of a few minutes ago, so
please let me know if anything strange happens.

----------------------------------------------------------------
Fixes for 5.7:
- Fix a partially uninitialized variable.
- Teach the background gc threads to apply for fsfreeze protection.
- Fix some scaling problems when multiple threads try to flush the
  filesystem when we're about to hit ENOSPC.
