From 8bac41cbfe2efe55e2b93673b84761ed7dd75f69 Mon Sep 17 00:00:00 2001 From: Stanislav Fomichev Date: Mon, 20 Jan 2014 15:39:39 +0400 Subject: [PATCH] perf session: Free cpu_map in perf_session__cpu_bitmap This method uses a temporary struct cpu_map to figure out the cpus present in the received cpu list in string form, but it failed to free it after returning. Fix it.
