# Merge: 4b6b51322118 1db7959aacd9
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'for-6.9-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fixes from David Sterba:
#     
#      - fixup in zoned mode for out-of-order writes of metadata that are no
#        longer necessary, this used to be tracked in a separate list but now
#        the old locaion needs to be zeroed out, also add assertions
#     
#      - fix bulk page allocation retry, this may stall after first failure
#        for compression read/write
#     
#     * tag 'for-6.9-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
#       btrfs: do not wait for short bulk allocation
#       btrfs: zoned: add ASSERT and WARN for EXTENT_BUFFER_ZONED_ZEROOUT handling
#       btrfs: zoned: do not flag ZEROOUT on non-dirty extent buffer
