From 7d94dddd438bcba97db44f120da39bb001b5249f Mon Sep 17 00:00:00 2001 From: Shailabh Nagar Date: Sun, 30 Jul 2006 03:03:10 -0700 Subject: [PATCH] make taskstats sending completely independent of delay accounting on/off status Complete the separation of delay accounting and taskstats by ignoring the return value of delay accounting functions that fill in parts of taskstats before it is sent out (either in response to a command or as part of a task exit). Also make delayacct_add_tsk return silently when delay accounting is turned off rather than treat it as an error.
