btrfs: add (the only possible) __exit annotation (ffc5a379) · Commits · 戴 / test

Recently, the __init annotations have been added. There's unfortunatelly only one case where we can add __exit, because most of the cleanup helpers are also called from the __init phase. As the __exit annotated functions get discarded completely for a built-in code, we'd miss them from the init phase. Signed-off-by:
