[PATCH v1 0/7] xprtrdma Send completion batching

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Jason, Sagi-

Here's an updated version of last week's patches to implement
strong Send Queue accounting and Send completion batching in
the Linux RPC-over-RDMA client implementation. I've addressed
Jason's concern about patch description language and Sagi's
concern about leaking data in Send buffers that are re-used
after RPC completion, in addition to a number of smaller
clean ups.

Also available as the first several commits in this topic branch:

http://git.linux-nfs.org/?p=cel/cel-2.6.git;a=shortlog;h=refs/heads/nfs-rdma-for-4.15


Changes since RFC:
* Replace "completion heartbeat" language in patch descriptions and
  code comments
* Ensure RPC completion waits for pages to be unmapped
* Remove incorrect clean up in rpcrdma_sendctxs_destroy
* Further clean up of rl_mapped_sges
* Create separate patch (description) for change in
  rpcrdma_prepare_hdr_sges
* Various micro-optimizations of branches and loops
