This was intended as a helper so that existing drivers can run through the sgt based mapping type flow without having to open code it. It is hardwired to only do sgt like this. If you want to use more than sgt as your mapping type don't use this function The point was to create a clear distinction in the API names when things were in a SGT-only flow vs using the newer negotiable flow. > > Signed-off-by: Jason Gunthorpe Alistair since you rebased it you should put your SOB on every patch...
