> The XDR class is one fundamental aspect in the current implementation of NFS
> server. While the client might potentially have a higher level APIs, it also
> requires redundant copying since the upstream clients have insufficient
> information.
> This JIRA introduces a new class, RpcInfo, which (1) decouples XDR from the
> APIs, turning it into a utility class, and (2) exposes ChannelBuffer directly
> to the client in order to open the opportunity for avoid copying.
