This case can cover bc37e4fb5cac (xfs: revert "xfs: actually bump warning counts when we send warnings"). And will help to expose later behavior changes on this side. Signed-off-by: Zorro Lang --- Thanks review points from Darrick, V2 move _create_project_quota and _restore_project_quota to common/quota and help them to be common.
