Subject: [PATCH v2 3/3] perf metric: Fix memory leaks.
Date: Sun, 7 Nov 2021 01:00:02 -0800 [thread overview]
Message-ID: <20211107090002.3784612-3-irogers@google.com> (raw)
In-Reply-To: <20211107090002.3784612-1-irogers@google.com>
Certain error paths may leak memory as caught by address sanitizer.
Ensure this is cleaned up to make sure address/leak sanitizer is happy.
Fixes: 5ecd5a0c7d1c ("perf metrics: Modify setup and deduplication")
