The following updated series modifies the RPC/RDMA (NFS/RDMA)
client to support the new rdma "fastreg" memory registration mode,
which fixes operation on the Chelsio cxgb3 adapter and strengthens
the safety of others. Additionally, it fixes many smaller issues
in the code improving its robustness and performance. Except for
supporting large (>32KB) rpc's, it addresses all known issues in
the client.
This updated patchset clarifies the author-vs-acked status of
the individual patches, tunes the git log text of some, and omits
the previous patch 12 ("5 second pause") which I'm currently
working on, as per comments.
This patchset applies to the current nfs-2.6 git;
(69849375d6b13e94d08cdc94b49b11fbab454a0e)
