In the email title: the generic/211 case of xfstests.

Here are the rough steps to reproduce the problem in KVM:

mkfs -t ext4 -q /dev/vda
mkfs -t ext4 -q /dev/vdd
mount -t ext4 /dev/vda /fs/vda
mount -t ext4 /dev/vdd /fs/vdd
export TEST_DIR=/fs/vda
export TEST_DEV=/dev/vda
export SCRATCH_DEV=/dev/vdd
export SCRATCH_MNT=/fs/scratch
mkdir /fs/scratch -p
./check generic/211

Thanks,
Fengguang
