I took the feedback from Christoph and Jason to mean I should remove ib_get_dma_mr() entirely and pull its guts into rdma_get_dma_mr(), and change all the users of ib_get_dma_mr() to use rdma_get_dma_mr(). So the net result isn't a wrapper. It would of course still use rdma_device_access_flags()...
