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
