Here are a couples of cleanups of things I observed while looking at the
extent_buffer management code.
Patch 1 rewrites a do {} while into a simple for() construct. This survived
xfstest + selftests
Patch 2 substitutes and outdated comment for a lockdep_assert_held call
Patch 3 rename the idiotic EXTENT_BUFFER_DUMMY to something more meaningful
Patch 4 removes some cargo-cult copied code when performing qgroup leaf scan
Nikolay Borisov (4):
btrfs: Refactor loop in btrfs_release_extent_buffer_page
btrfs: Document locking require via lockdep_assert_held
btrfs: Rename EXTENT_BUFFER_DUMMY to EXTENT_BUFFER_PRIVATE
btrfs: Remove unnecessary locking code in qgroup_rescan_leaf
