Subject: [PATCH 3/6] Btrfs: free all recorded tree blocks on error
Date: Tue,  5 Mar 2013 00:25:38 +0800	[thread overview]
Message-ID: <1362414341-17306-4-git-send-email-bo.li.liu@oracle.com> (raw)
In-Reply-To: <1362414341-17306-1-git-send-email-bo.li.liu@oracle.com>

We've missed the 'free blocks' part on ENOMEM error.
