  gfs2: Recover statfs info in journal head (2020-10-23 15:47:38 +0200)

----------------------------------------------------------------
Changes in gfs2:
* Use iomap for non-journaled buffered I/O.  This largely eliminates buffer
  heads on filesystems where the block size matches the page size.  Many thanks
  to Christoph Hellwig for this patch!
* Fixes for some more journaled data filesystem bugs, found by running xfstests
  with data journaling on for all files (chattr +j $MNT) (Bob Peterson).
* gfs2_evict_inode refactoring (Bob Peterson).
* Use the statfs data in the journal during recovery instead of reading it in
  from the local statfs inodes (Abhi Das).
* Several other minor fixes by various people.

----------------------------------------------------------------
Abhi Das (3):
      gfs2: Add fields for statfs info in struct gfs2_log_header_host
      gfs2: lookup local statfs inodes prior to journal recovery
