[GIT PULL] GFS2 changes for 5.12

[Andreas Gruenbacher]

Hi Linus,

please consider pulling the following gfs2 changes for 5.12.  My apologies for
the late request; we ended up getting stuck with two broken patches that have
now both been removed.

Thanks a lot,
Andreas

  gfs2: Don't get stuck with I/O plugged in gfs2_ail1_flush (2021-02-23 19:01:42 +0100)

----------------------------------------------------------------
Changes in gfs2:
* Log space and revoke accounting rework to fix some failed asserts.
* Local resource group glock sharing for better local performance.
* Add support for version 1802 filesystems: trusted xattr support and
  '-o rgrplvb' mounts by default.
* Actually synchronize on the inode glock's FREEING bit during withdraw
  ("gfs2: fix glock confusion in function signal_our_withdraw").
* Fix parallel recovery of multiple journals ("gfs2: keep bios separate
  for each journal").
* Various other bug fixes.
