Merge tag 'for-6.4-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs fixes from David Sterba:
 "One bug fix and two build warning fixes:

   - call proper end bio callback for metadata RAID0 in a rare case of
     an unaligned block

   - fix uninitialized variable (reported by gcc 10.2)

   - fix warning about potential access beyond array bounds on mips64
     with 64k pages (runtime check would not allow that)"

* tag 'for-6.4-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
  btrfs: fix csum_tree_block page iteration to avoid tripping on -Werror=array-bounds
  btrfs: fix an uninitialized variable warning in btrfs_log_inode
  btrfs: call btrfs_orig_bbio_end_io in btrfs_end_bio_work
