Hi Kemeng,

If you need help running xfstests, I maintain a test appliance which
makes it very easy to run xfstests on development kernels.  Please see:

This test appliance can also be run on Android devices and using
Google Compute Engine; for more information see:

If you're just getting started, I recommend that you start with
kvm-xfstests, and this is the simplest way to get started.
