Subject: [PATCH 7/9] Btrfs: qgroup: make the btree for qgroup increase from left to right.
Date: Tue, 10 Feb 2015 18:23:21 +0800 [thread overview]
Message-ID: <1423563803-8996-10-git-send-email-yangds.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1423563803-8996-1-git-send-email-yangds.fnst@cn.fujitsu.com>
It's not a big deal, but I would rather make the btree follow the
convention to increase from left to right.
