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.
