>The following series updates 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.
>
>It's my hope this patchset can be queued for the upcoming merge
>window. It has been extensively tested with both IB and iWARP
>adapters under Connectathon and heavy parallel load.

>This patchset applies to the current nfs-2.6 git;
