If the DISCARD of the thin device somehow fails with this message: device-mapper: thin: Data device (dm-1) discard unsupported: Disabling discard passdown. Then we can end up with arbitrary gunk in the thin device. This causes mkfs to fail because it's afraid to format the device. Don't be afraid, just zap it. FWIW mkfs.xfs thinks that the thinp device has an xfs external log because sometimes the thinp device just happen to be backed by the log of the previous test's scratch fs. Signed-off-by: Darrick J.
