sizeof(struct ib_send_wr) (old): 96 sizeof(struct ib_send_wr): 48 sizeof(struct ib_rdma_wr): 64 sizeof(struct ib_atomic_wr): 96 sizeof(struct ib_ud_wr): 88 sizeof(struct ib_fast_reg_wr): 88 sizeof(struct ib_bind_mw_wr): 96 sizeof(struct ib_sig_handover_wr): 80 sizeof(struct ib_fastreg_wr) (Sagi): 64 So the commonly used send and rdma WRs are drastically redueces. FR currently doesn't look much better, but the replacement WR for it in Sagi's series will be in a simila ballpark. Note that we can remove an additional 4 bytes from each of them by removing the unused xrc_remote_srq_num value from struct ib_send_wr. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
