FWIW, this will conflict with Josef's new btrfs/308 patch. You don't
have to use monatomically increasing numbers for the tests anymore
in the fileystem specifc test directories - you could make these
tests btrfs/00[1-4].... :)
Cheers,
Dave.

I'm not sure if "-F" is still needed after commit

Here too, maybe we can drop "-F" option?
Also 309 has this issue too. 310 and 311 are fine.

Right, it's not, oops. :( Old habits (and old patch, TBH)
I can fix & resend all of them I guess.
