Qu Wenruo 1d2beaa95b btrfs: qgroup: Add comments explaining how btrfs qgroup works ... Add explaination how btrfs qgroups work. Qgroup is split into 3 main phrases: 1) Reserve To ensure qgroup doesn't exceed its limit 2) Trace To info qgroup to trace which extent 3) Account Calculate qgroup number change for each traced extent. This should save quite some time for new developers.
