[4.4][PATCH 0/3] btrfs: Qgroup hotfix

[Qu Wenruo <quwenruo@cn.fujitsu.com>]

This patchset fixes 2 bugs:
1. Race condition leading to abort transaction
Reported by Filipe, fixed by 2nd patch.

2. Qgroup low level double free leading to EDQUOT
In fact, I hit such bug several times during internal rebase, but I'm so
stupid to forgot to include it in v3 patchset.
Fixed in 3rd patch.

Qu Wenruo (3):
  btrfs: Cleanup no_quota parameter
  btrfs: qgroup: Fix a race in delayed_ref which leads to abort trans
  btrfs: qgroup: Fix a rebase bug which will cause qgroup double free
