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.
