From ef759a2e54ed434b2f72b52a14edecd6d4eadf74 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 20 Mar 2006 13:44:17 -0500 Subject: SUNRPC: introduce per-task RPC iostats Account for various things that occur while an RPC task is executed. Separate timers for RPC round trip and RPC execution time show how long RPC requests wait in queue before being sent. Eventually these will be accumulated at xprt_release time in one place where they can be viewed from userland. Test plan: Compile kernel with CONFIG_NFS enabled.
