From 3beb0861438f63bc2025f8afba213dc3d0458bc5 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 15 Mar 2013 14:48:50 +0900 Subject: [PATCH] perf trace: Free evlist resources properly on return path The trace_run() function calls several evlist functions but misses some pair-wise cleanup routines on return path. Fix it.
