This series creates a new helper API for draining a queue pair. It is a rework of an original patch created by Christoph Hellwig as part of the CQ API rework and was dropped to be resubmitted by me with iw_cxgb4 support. Original thread: http://www.spinics.net/lists/linux-rdma/msg30296.html Changes since v1: - added comments to the ib_drain_qp() function header specifying the consumer requirements - in __ib_drain_qp(), if the ib_post_send() fails, still wait for the recv wr to drain since we already posted it. - CC the SRP maintainer, bart.vanassche@xxxxxxxxxxx. --- Steve Wise (3): IB: new common API for draining a queue pair iw_cxgb4: add drain_qp function IB/srp: use ib_drain_qp() drivers/infiniband/core/verbs.c | 77 ++++++++++++++++++++++++++++++++++ drivers/infiniband/hw/cxgb4/cq.c | 6 ++- drivers/infiniband/hw/cxgb4/iw_cxgb4.h | 2 + drivers/infiniband/hw/cxgb4/provider.c | 1 + drivers/infiniband/hw/cxgb4/qp.c | 8 ++++ drivers/infiniband/ulp/srp/ib_srp.c | 45 ++++---------------- include/rdma/ib_verbs.h | 2 + 7 files changed, 102 insertions(+), 39 deletions(-) -- 2.7.0 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
