Pull btrfs fixes from David Sterba:

 - fix -Warray-bounds warning, to help external patchset to make it
   default treewide

 - fix writeable device accounting (syzbot report)

 - fix fsync and log replay after a rename and inode eviction

 - fix potentially lost error code when submitting multiple bios for
   compressed range

* tag 'for-5.14-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
  btrfs: calculate number of eb pages properly in csum_tree_block
  btrfs: fix rw device counting in __btrfs_free_extra_devids
  btrfs: fix lost inode on log replay after mix of fsync, rename and inode eviction
  btrfs: mark compressed range uptodate only if all bio succeed
