From ac5c93005b7073732e268606688fb6c821d5310e Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Thu, 27 Dec 2012 09:01:24 +0000 Subject: Btrfs: let allocation start from the right raid type 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).
