But as this just affects zoned devices on btrfs for now I guess the usual parties can just make sure it works by backporting the right patches. The previous don't work wasn't even a not supported, but a case of dm-error being buggy for zoned devices. In other words the original exclusion in xfstests should have never gone in and whoever put it there should have fixed dm-error instead.
