Use with caution. > ------------------------------------------------------------------------ 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....
