Subject: [PATCH 06/11] perf test: Fix memory leaks in parse-metric test
Date: Tue, 15 Sep 2020 12:18:14 +0900	[thread overview]
Message-ID: <20200915031819.386559-7-namhyung@kernel.org> (raw)
In-Reply-To: <20200915031819.386559-1-namhyung@kernel.org>

It didn't release resources when there's an error so the
test_recursion_fail() will leak some memory.

Acked-by: Jiri Olsa <jolsa@redhat.com>
Fixes: 0a507af9c681a ("perf tests: Add parse metric test for ipc metric")
Signed-off-by: Namhyung Kim <namhyung@kernel.org>
