Many tests use dm_flakey to trigger log replay, but for filesystems that don't support metadata journaling, this causes failures when it shouldn't. (i.e. we can hardly test log replay if there is no log, and the subsequent filesystem check will turn up errors). For some tests they actually sync everything we care about, and find inconsistencies elsewhere, but I erred on the side of simply not running the test in most cases.
