Hmm. Resolving that conflict, I just reacted to how the st.c code
passes in a NULL gendisk to scsi_ioctl() and then on to
blk_execute_rq().

Just checking that was fine, and I notice how *many* places do that.

Should the blk_execute_rq() function even take that "struct gendisk
*bd_disk" argument at all?

Maybe the right thing to do would be for the people who care to just
set rq->rq_disk before starting the request..

But I guess it's traditional, and nobody cares.
