Date: Thu, 20 Nov 2014 09:15:34 +0900 From: byungchul.park@....com To: rostedt@...dmis.org Cc: mingo@...hat.com, linux-kernel@...r.kernel.org, seungho1.park@....com, jolsa@...hat.com, Byungchul Park <byungchul.park@....com> Subject: [PATCH v5 1/2] tracing, function_graph: fix micro seconds notation in comment From: Byungchul Park <byungchul.park@....com> 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.
