Hmm, I did a quick pass through the code and the only place this seems
to be used, is to pass it to blk_verify_command() if the subcommand used
in the BSG request is a SCSI Command. And this has the same semantics.
So I guess this would require adjustments to the whole stack, as this is
also used from the 'normal' SG side of the world.
