With PATCH 1/2 applied, per-RPC RT latency improves by about three microseconds, a substantial benefit for small RPCs on typical fabrics. I have one more RPC/RDMA patch for v4.17 that is a recent fix. It is waiting for linux-rdma review and maybe a Tested-by. --- Chuck Lever (2): xprtrdma: Move Receive posting to rpcrdma_reply_handler xprtrdma: Add static trace point in post_recvs include/trace/events/rpcrdma.h | 40 ++++++++-- net/sunrpc/xprtrdma/backchannel.c | 10 +- net/sunrpc/xprtrdma/rpc_rdma.c | 17 ++-- net/sunrpc/xprtrdma/transport.c | 3 - net/sunrpc/xprtrdma/verbs.c | 154 ++++++++++++++----------------------- net/sunrpc/xprtrdma/xprt_rdma.h | 7 -- 6 files changed, 108 insertions(+), 123 deletions(-) -- Chuck Lever
