From 063c54dccdecb0479662778ddf54ee45aa55423d Mon Sep 17 00:00:00 2001 From: Gui Hecheng Date: Fri, 9 Jan 2015 09:39:40 +0800 Subject: [PATCH] btrfs: fix raid56 scrub failed in xfstests btrfs/072 The xfstests btrfs/072 reports uncorrectable read errors in dmesg, because scrub forgets to use commit_root for parity scrub routine and scrub attempts to scrub those extents items whose contents are not fully on disk. To fix it, we just add the @search_commit_root flag back.
