Subject: [PATCH v1 00/22] convert NFS server to new rdma_rw API
Date: Sat, 07 Jan 2017 12:15:15 -0500	[thread overview]
Message-ID: <20170107170258.14126.8503.stgit@klimt.1015granger.net> (raw)

This series converts the Linux NFS server RPC-over-RDMA
implementation to use the new core rdma_rw API and to poll its CQs
in workqueue mode.

Previously published work prototyped only the path that sends RPC
replies. This series converts both send and receive sides, and
includes significant clean ups that result from using the new API.

This series has been successfully tested with NFSv3, 4.0, and 4.1;
with clients that use FRWR and FMR; and with sec=sys, krb5, krb5i,
and krb5p.

Available in the "nfsd-rdma-rw-api" topic branch of this git repo:

git://git.linux-nfs.org/projects/cel/cel-2.6.git
