So we should be able to fix the block size to be 1k, which would allow us to use a smaller dmhugedisk, and then skip this test if dax is enabled. OTOH, generic/620 runs pretty quicky, so perhaps it's better to do thie quick fix: hardcode the block size to 4k, and then skip it if dax && page_size != 4k. - Ted
