From 43f8e76e6b96eb1327cff62ac1cc733a51f31068 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 25 Jan 2013 10:44:44 +0900 Subject: [PATCH] perf evsel: Fix memory leaks on evsel->counts The ->counts field was never freed in the current code. Add perf_evsel__free_counts() function to free it properly.
