Merge tag 'gfs2-for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2

Pull gfs2 updates from Andreas Gruenbacher:

 - Use asynchronous glocks and timeouts to recover from deadlocks during
   rename and exchange: the lock ordering constraints the vfs uses are
   not sufficient to prevent deadlocks across multiple nodes.

 - Add support for IOMAP_ZERO and use iomap_zero_range to replace gfs2
   specific code.

 - Various other minor fixes and cleanups.
