BTRFS qgroup deletion when deleting subvolume should be handled by kernel. #627
Description
/kind bug
Description
While deleting a subvolume on btrfs with qgroup enabled, current behavior is deleting qgroup explicitly before deleting the subvolume.
However, from arch's document.
Note
Qgroups corresponding to subvolumes cannot be deleted directly, but should be automatically deleted by directly deleting the subvolume.
Also, in btrfs-progs, deleting a subvolume doesn't delete the qgroup.
