From 5710fcad7c367adefe5634dc998f1f88780a8457 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Wed, 21 Apr 2010 18:06:01 +0200 Subject: [PATCH] perf: Fix initialization bug in parse_single_tracepoint_event() The parse_single_tracepoint_event() was setting some attributes before it validated the event was indeed a tracepoint event. This caused problems with other initialization routines like in the builtin-top.c module whereby sample_period is not set if not 0.
