SUNRPC: display human-readable procedure name in rpc_iostats output
Add fields to the rpc_procinfo struct that allow the display of a human-readable name for each procedure in the rpc_iostats output. Also fix it so that the NFSv4 stats are broken up correctly by sub-procedure number. NFSv4 uses only two real RPC procedures: NULL, and COMPOUND. Test plan: Mount with NFSv2, NFSv3, and NFSv4, and do "cat /proc/self/mountstats". Signed-off-by: Chuck Lever <cel@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
