The purpose of this series is to prepare for the optimization of svc_process_common() to handle NFSD workloads more efficiently. In other words, NFSD should be the lubricated common case, and callback is the use case that takes exceptional paths. Note: For the moment these are compile-tested only. There are some additional clean-ups that will be possible once this series is merged.
