[PATCH v4 1/3] tracing, function_graph: fix micro seconds notation in comment

From: byungchul . park
Date: Tue Nov 18 2014 - 00:57:36 EST


From: Byungchul Park <byungchul.park@xxxxxxx>

Usually, "msecs" notation means milli-seconds, and "usecs" notation
means micro-seconds. Since the unit used in the code is micro-seconds,
the notation should be replaced from msecs to usecs.
