Here are some clean-ups and minor optimizations for svcrdma, in addition to two patches that reduce the likelihood of connection loss on heavy workloads (the final two patches in the series). svcrdma appears to under-allocate Send Queue resources, which will cause NFSD to drop the connection occasionally. This results in a burp in the Send pipeline and a loss of throughput. The series (including these patches) is in the svcrdma-next branch of: https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git --- Chuck Lever (8): svcrdma: De-duplicate completion ID initialization helpers svcrdma: Optimize svc_rdma_cc_init() svcrdma: Remove pointer addresses shown in dprintk() svcrdma: Remove queue-shortening warnings svcrdma: Clean up comment in svc_rdma_accept() svcrdma: Reserve an extra WQE for ib_drain_rq() svcrdma: Use all allocated Send Queue entries svcrdma: Increase the per-transport rw_ctx count include/linux/sunrpc/svc_rdma.h | 24 ++++++++ net/sunrpc/xprtrdma/svc_rdma_recvfrom.c | 9 +-- net/sunrpc/xprtrdma/svc_rdma_rw.c | 16 ++--- net/sunrpc/xprtrdma/svc_rdma_sendto.c | 9 +-- net/sunrpc/xprtrdma/svc_rdma_transport.c | 75 ++++++++++++++---------- 5 files changed, 74 insertions(+), 59 deletions(-) -- Chuck Lever
