A quick look shows that this could be the SCSI_SYNCHRONIZE_CACHE_10
(BTW, this means that right now, no cache sync is done for ciss I guess),
which can be worked around with the PQUIRK_NOSYNCCACHE quirk.
sd_getcache()/sd_setcache() could also issue version 2-only commands, but
AFAIK these are only called for user IOCTLs.
