I like this too, but, I'm a little worried this makes the API more confusing - ideally, we'd get rid of all the IB_ACCESS stuff from within the kernel completely. Then it make sense, the mr is created as a rkey/lkey mr, the single return is only one kind, and that kind must go in the lkey/rkey spots in other API places.
