#     Merge tag 'for-5.4-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fixes from David Sterba:
#      "A few regressions and fixes for stable.
#     
#       Regressions:
#     
#        - fix a race leading to metadata space leak after task received a
#          signal
#     
#        - un-deprecate 2 ioctls, marked as deprecated by mistake
#     
#       Fixes:
#     
#        - fix limit check for number of devices during chunk allocation
#     
#        - fix a race due to double evaluation of i_size_read inside max()
#          macro, can cause a crash
#     
#        - remove wrong device id check in tree-checker"
#     
#     * tag 'for-5.4-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
#       btrfs: un-deprecate ioctls START_SYNC and WAIT_SYNC
