[PATCH v3 00/11] NFS/RDMA client patches for v4.6

[Chuck Lever <chuck.lever@oracle.com>]

Hi Anna-

These are ready for you to take.

There continues to be some fallout from enabling NFSv4.1/RDMA, and
from converting the reply handler to use a work queue.  This series
includes some bug fixes for those issues.

Logic to handle the RPC-over-RDMA RDMA_ERROR message type is also
introduced into the RPC reply handler.

Also included is a patch set to convert xprtrdma to use the new core
CQ API.

Available in the "nfs-rdma-for-4.6" topic branch of this git repo:

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

Or for browsing:
