SUNRPC: provide a mechanism for collecting stats in the RPC client
Add a simple mechanism for collecting stats in the RPC client. Stats are tabulated during xprt_release. Note that per_cpu shenanigans are not required here because the RPC client already serializes on the transport write lock. Test plan: Compile kernel with CONFIG_NFS enabled. Basic performance regression testing with high-speed networking and high performance server. Signed-off-by: Chuck Lever <cel@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
