Li Zhijian 911965ace9 migration/rdma: advise prefetch write for ODP region ... The responder mr registering with ODP will sent RNR NAK back to the requester in the face of the page fault. --------- ibv_poll_cq wc.status=13 RNR retry counter exceeded! ibv_poll_cq wrid=WRITE RDMA! --------- ibv_advise_mr(3) helps to make pages present before the actual IO is conducted so that the responder does page fault as little as possible.
