The following set of patches fix known issues with the 2.6.7-rc1 NFS client code, and significantly enhance the support for NFSv4.
NFSv4: Prime SETCLIENTID call for the delegation callback info.
RPC: Convert rpciod into a work queue for greater flexibility.
RPC: Remove the rpc_queue_lock global spinlock. Replace it with per-rpc_queue spinlocks
NFSv2/v3/v4: Place NFS nfs_page shared data into a single structure that hangs off filp->private_data. As a side effect, this also cleans up the NFSv4 private file state info.
NFSv4: More cleanups of the NFSv4 state.
All of the above patches rolled into one.
NFSv4: Basic code for managing delegation state.
NFSv4: Delegation callback server.
