From e622f2f4ad2142d2a613a57fb85f8cf737935ef5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 8 Oct 2015 09:16:33 +0100 Subject: IB: split struct ib_send_wr This patch split up struct ib_send_wr so that all non-trivial verbs use their own structure which embedds struct ib_send_wr. This dramaticly shrinks the size of a WR for most common operations: 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 And with Sagi's pending MR rework the fast registration WR will also be down to a reasonable size: sizeof(struct ib_fastreg_wr): 64 Signed-off-by: Christoph Hellwig Reviewed-by: Bart Van Assche [srp, srpt] Reviewed-by: Chuck Lever [sunrpc] Tested-by: Haggai Eran Tested-by: Sagi Grimberg Tested-by: Steve Wise --- drivers/infiniband/ulp/isert/ib_isert.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'drivers/infiniband/ulp/isert/ib_isert.h') diff --git a/drivers/infiniband/ulp/isert/ib_isert.h b/drivers/infiniband/ulp/isert/ib_isert.h index 6a04ba3c0f72..0a4a7861cce9 100644 --- a/drivers/infiniband/ulp/isert/ib_isert.h +++ b/drivers/infiniband/ulp/isert/ib_isert.h @@ -118,9 +118,9 @@ struct isert_rdma_wr { enum iser_ib_op_code iser_ib_op; struct ib_sge *ib_sge; struct ib_sge s_ib_sge; - int send_wr_num; - struct ib_send_wr *send_wr; - struct ib_send_wr s_send_wr; + int rdma_wr_num; + struct ib_rdma_wr *rdma_wr; + struct ib_rdma_wr s_rdma_wr; struct ib_sge ib_sg[3]; struct isert_data_buf data; struct isert_data_buf prot; -- cgit v1.2.3-59-g8ed1b
