Subject: [PATCH v2 13/26] perf evlist: Free stats in all evlist destruction
Date: Thu, 8 Jun 2023 16:28:10 -0700 [thread overview]
Message-ID: <20230608232823.4027869-14-irogers@google.com> (raw)
In-Reply-To: <20230608232823.4027869-1-irogers@google.com>
There is no evsel free stats, freeing in the evlist__delete ensures
memory leaks are avoided. Issues detected with "perf stat report" and
leak sanitizer, perf stat uses perf_session__delete to free the
evlist. Add dummy symbol for python build.
