Date: Mon, 13 Nov 2017 01:38:07 +0000 From: Wang Nan <wangnan0@...wei.com> To: <linux-kernel@...r.kernel.org>, <kan.liang@...el.com>, <acme@...nel.org>, <jolsa@...hat.com>, <namhyung@...nel.org> CC: Wang Nan <wangnan0@...wei.com> Subject: [PATCH 5/7] perf tests: Set evlist of test__task_exit() to !overwrite Changing ringbuffer to !overwrite in this task is harmless because this test uses a very low frequency (1) and using a very simple program (true). There should have only 3 events in the whole test. Overwriting is impossible to happen.
