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 <hch@lst.de> Reviewed-by: Bart Van Assche <bart.vanassche@sandisk.com> [srp, srpt] Reviewed-by: Chuck Lever <chuck.lever@oracle.com> [sunrpc] Tested-by: Haggai Eran <haggaie@mellanox.com> Tested-by: Sagi Grimberg <sagig@mellanox.com> Tested-by: Steve Wise <swise@opengridcomputing.com>
