#     Merge tag 'for-5.6-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fixes from David Sterba:
#      "These are fixes that were found during testing with help of error
#       injection, plus some other stable material.
#     
#       There's a fixup to patch added to rc1 causing locking in wrong context
#       warnings, tests found one more deadlock scenario. The patches are
#       tagged for stable, two of them now in the queue but we'd like all
#       three released at the same time.
#     
#       I'm not happy about fixes to fixes in such a fast succession during
#       rcs, but I hope we found all the fallouts of commit 28553fa992cb
#       ('Btrfs: fix race between shrinking truncate and fiemap')"
