Sorry I didn't provide the test steps:
1) git clone git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git
2) cd xfstests-dev
3) make -j8 # refer to README, about how to build xfstests
4) vi local.config
# The FSTYP can be other fs, e.g. ext4.
# The TEST_DEV and SCRATCH_DEV can be any local devices you have (even loopdev)
# TEST_DIR and SCRATCH_MNT can be changed too
export FSTYP=xfs
export TEST_DEV=/dev/sda5
export TEST_DIR=/mnt/test
export SCRATCH_DEV=/dev/sda3
export SCRATCH_MNT=/mnt/scratch
5) mkfs.xfs -f /dev/sda5 && mkfs.xfs -f /dev/sda3
6) mkdir -p /mnt/test && mkdir -p /mnt/scratch
7) ./check -overlay generic/617
The step#6 will be failed.
Thanks,
Zorro
