Subject: [4.4][PATCH 0/3] btrfs: Qgroup hotfix
Date: Mon, 26 Oct 2015 14:08:32 +0800 [thread overview]
Message-ID: <1445839715-17495-1-git-send-email-quwenruo@cn.fujitsu.com> (raw)
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
