[PATCH V2] xfstest: an regression test for btrfs balance
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 Signed-off-by: Gui Hecheng <guihc.fnst@cn.fujitsu.com> Reviewed-by: Josef Bacik <jbacik@fusionio.com> --- Changelog V1->V2 change test number 319 -> 012 --- tests/btrfs/012 | 71 +++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/btrfs/012.out | 2 ++ tests/btrfs/group | 1 + 3 files changed, 74 insertions(+) create mode 100755 tests/btrfs/012 create mode 100644 tests/btrfs/012.out diff --git a/tests/btrfs/012 b/tests/btrfs/012 new file mode 100755 index 0000000..19a6c99 --- /dev/null +++ b/tests/btrfs/012 @@ -0,0 +1,71 @@ +#! /bin/bash +# FS QA Test No. btrfs/012 +# +# Btrfs balance tests +# +#----------------------------------------------------------------------- +# Copyright (c) 2013 Fujitsu.
