Subject: [PATCH 2/9] btrfs: qgroup: inherit limit info from srcgroup in creating snapshot.
Date: Tue, 10 Feb 2015 18:23:16 +0800 [thread overview]
Message-ID: <1423563803-8996-5-git-send-email-yangds.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1423563803-8996-1-git-send-email-yangds.fnst@cn.fujitsu.com>
Currently, when we snapshot a subvol, snapshot will not copy the limits
from srcqgroup.
This patch make the qgroup in snapshot inherit the limit info when create
a snapshot.
