Originally, when executing "btrfs balance" right after "btrfs subvolume snaphot" & "btrfs subvolume delete", a kernel BUG arises. This problem is caused by the patch: [PATCH 1/2] Btrfs: fix for patch "cleanup: don't check the same thing twice" The commit id: 48475471728f060bfd2e686f592ef208d3ba8b7d (in kernel/git/torvalds/linux.git) handled by the patch: [PATCH 2/3] Btrfs: fix oops caused by the space balance and dead roots [rjohnston: change test number to 14] Signed-off-by: Gui Hecheng <guihc.fnst@cn.fujitsu.com> Reviewed-by: Josef Bacik <jbacik@fusionio.com> Signed-off-by: Rich Johnston <rjohnston@sgi.com>
