Currently DATA cdbs are those that get passes through to the
backend (except for pscsi which gets all of them). As the backends
can't handle WRITE_SAME this patch is incorrect.
I have a nice prototype to kill that whole DATA vs CONTROL flag thing,
which will be much nicer after your series. Once the guts of your
patches hit the tree I'll resubmit them.
