Hi Jan,

With this patch applies, xfstests is hanging after ext4/001 runs:

BEGIN TEST: Ext4 4k block Tue May 20 03:18:49 UTC 2014
Device: /dev/vdb
mk2fs options: -q
mount options: -o block_validity
FSTYP         -- ext4
PLATFORM      -- Linux/i686 candygram 3.15.0-rc2-00052-g0f430fc
MKFS_OPTIONS  -- -q /dev/vdc
MOUNT_OPTIONS -- -o acl,user_xattr -o block_validity /dev/vdc /vdc

ext4/001 4s ...	 [03:19:05] [03:19:09] 4s

It just stops here, and never runs the next test.

If I revert this commit, the test run continus with ext4/002, and then
onto the rest of the tests.

Could you take a look?

Thanks!!
