From cc0175c1dc1de8f6af0eb0631dcc5b999a6fcc42 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 20 Mar 2006 13:44:22 -0500 Subject: 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".
