From 4dc1024a7a529626de5a800b10088bcbbc1ae941 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 6 Apr 2012 00:47:57 +0200 Subject: [PATCH] perf/events: Add flag to produce nsec output libtraceevent library prints out in usecs but perf wants to print out in nsecs. Add a flag that lets the user decide to print out in usec or nsec times.
