Anyway, here is the full set I'd like to see merged in that release. Along with the Receive efficiency-related patches that did not get into v4.17, there are a number of unrelated fixes, improve- ments, and clean ups in this series. There is a three-patch series near the end that handles the "empty sendctx queue" case a little more nicely. Instead of waiting an arbitrary amount of time and trying again, an RPC waits for the transport to wake it up when there are more sendctxs available. I've found this makes the transport a little less prone to deadlock under heavy workloads. As usual, the series can be found in my git repo as well: http://git.linux-nfs.org/?p=cel/cel-2.6.git;a=shortlog;h=refs/heads/nfs-rdma-for-4.18 --- Chuck Lever (19): xprtrdma: Add proper SPDX tags for NetApp-contributed source xprtrdma: Try to fail quickly if proto=rdma xprtrdma: Create transport's CM ID in the correct network namespace xprtrdma: Fix max_send_wr computation SUNRPC: Initialize rpc_rqst outside of xprt->reserve_lock SUNRPC: Add a ->free_slot transport callout xprtrdma: Introduce ->alloc_slot call-out for xprtrdma xprtrdma: Make rpc_rqst part of rpcrdma_req xprtrdma: Clean up Receive trace points xprtrdma: Move Receive posting to Receive handler xprtrdma: Remove rpcrdma_ep_{post_recv,post_extra_recv} xprtrdma: Remove rpcrdma_buffer_get_req_locked() xprtrdma: Remove rpcrdma_buffer_get_rep_locked() xprtrdma: Make rpcrdma_sendctx_put_locked() a static function xprtrdma: Return -ENOBUFS when no pages are available xprtrdma: Move common wait_for_buffer_space call to parent function xprtrdma: Wait on empty sendctx queue xprtrdma: Add trace_xprtrdma_dma_map(mr) xprtrdma: Remove transfertypes array include/linux/sunrpc/rpc_rdma.h | 1 include/linux/sunrpc/xprt.h | 6 - include/linux/sunrpc/xprtrdma.h | 1 include/trace/events/rpcrdma.h | 76 +++++-- net/sunrpc/clnt.c | 1 net/sunrpc/xprt.c | 17 +- net/sunrpc/xprtrdma/backchannel.c | 105 ++++------ net/sunrpc/xprtrdma/fmr_ops.c | 23 ++ net/sunrpc/xprtrdma/frwr_ops.c | 31 +++ net/sunrpc/xprtrdma/module.c | 1 net/sunrpc/xprtrdma/rpc_rdma.c | 66 ++---- net/sunrpc/xprtrdma/svc_rdma_backchannel.c | 1 net/sunrpc/xprtrdma/transport.c | 64 +++++- net/sunrpc/xprtrdma/verbs.c | 291 +++++++++++----------------- net/sunrpc/xprtrdma/xprt_rdma.h | 26 +-- net/sunrpc/xprtsock.c | 4 16 files changed, 359 insertions(+), 355 deletions(-) -- Chuck Lever
