Subject: [PATCH 08/20] perf env: fix memory leak of cpu_pmu_caps
Date:   Thu, 15 Jul 2021 18:07:13 +0200
Message-Id: <6ba036a8220156ec1f3d6be3e5d25920f6145028.1626343282.git.rickyman7@gmail.com>

ASan reports memory leaks while running the perf test
"83: Zstd perf.data compression/decompression".
The first of the leaks is caused by env->cpu_pmu_caps not being freed.

This patch adds the missing (z)free inside perf_env__exit.
