From 74922be1485818ed368c4cf4f0b100f70bf01e08 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sun, 7 Oct 2007 00:24:31 -0700 Subject: [PATCH] Fix timer_stats printout of events/sec When using /proc/timer_stats on ppc64 I noticed the events/sec field wasnt accurate. Sometimes the integer part was incorrect due to rounding (we werent taking the fractional seconds into consideration). The fraction part is also wrong, we need to pad the printf statement and take the bottom three digits of 1000 times the value.
