You could, but the result would not be what you expect, given that every /dev/sd* device and more in Linux support it. What we really need is to stop shoe-horning scsi pass through support into the block layer. Once we finally get our generic thread offload facilily there is no need for it anymore at all, scsi-generic can simplify offload the SG_IO ioctl and be done with it. I even have an old prototype for this, just waiting for the generic thread offload to get merged before resurrecting it.
