# Merge: fbc246a12aac f0b444b349e3
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     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.
