It gets quite a long way through xfstests here before there's
an assert failure in the rt summary locking code. I'm planning on
fixing that when I get a chance and then running xfstests on it
regularly.
I also have patches for xfstests that allow the config section
code to use external devices, which makes it somewhat easier to
have a "forget+test" config....
Cheers,
Dave.
