Subject: [PATCH 8/8] Btrfs: let allocation start from the right raid type
Date: Thu, 27 Dec 2012 17:01:24 +0800 [thread overview]
Message-ID: <1356598884-22952-8-git-send-email-bo.li.liu@oracle.com> (raw)
In-Reply-To: <1356598884-22952-1-git-send-email-bo.li.liu@oracle.com>
This'd avoid us empty looping.
Say we have only one disk and the metadata raid type will be defaultly DUP,
and we do not need to start from index=0(RAID10) and get over two empty
loops to index=2(DUP).
