[PATCH v1 00/13] NFS/RDMA patches for 3.17

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

The main purpose of this series is to address more connection drop
recovery issues by fixing FRMR re-use to make it less likely the
client will drop the connection due to a memory operation error.

Some other clean-ups and fixes are present as well.

See topic branch nfs-rdma-for-3.17 in

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

I tested with NFSv3 and NFSv4 on all three supported memory
registration modes. Used cthon04 and iozone with both Solaris
and Linux NFS/RDMA servers. Used xfstests with Linux.
