Sure, one could do if (key == mr->lkey) .. check lkey flags in the post, but that seems silly considering we want the post inlined.. > I can move it to the post interface if it makes more sense. > the access is kind of out of place in the mapping routine anyway... All the dma routines have an access equivalent during map, I don't think it is out of place.. To my mind, the map is the point where the MR should crystallize into an rkey or lkey MR, not at the post.
