I tried to get that out of the micron folks a while ago but don't
remember getting an answer. If that's actually tree please remove
the (misnamed) barrier argument from mtip_hw_submit_io, and maybe add
a comment that the current hardware can't have a volatile write cache.
Btw, does the hardware claim to have writeback caches in the ATA
IDENTIFY words related to it?
