From 618a3f1d30ea0ee2ff3a88661b8d6a4035123211 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 5 Sep 2012 14:02:48 +0900 Subject: [PATCH] perf header: Set tracepoint event name only if not set The event name can be set already by processing a event_desc data. So check it before setting to prevent possible leak.
