Thanks! I'm going to test it now. I've been running a stress test
from Chris Mason which basically checks races on parallel writes/read.

If this testsuite includes more checks, like xattr and some other
things, then that's exactly what I was searching.

I guess this is the right place to get it?

Thanks.
