Actually, currently they are. The primary reason is that we handle current SATA devices through SCSI via SAT, so we're going to have to do UNMAP for both arrays and SSDs until such time as SATA is ejected from the SCSI mid-layer and it can do trim on its own. The other reason, of course, is that we're mapping the Block layer discard statement for both as well. If that needs to change to two separate instructions, I don't think that's on our current radar. So, currently we're approaching this problem as one and I don't see any way we could logically separate the two cases (except by distinguishing between them with device parametrisation).
