[PATCH 54/83] perf tests: Set evlist of test__task_exit() to !overwrite
From: Arnaldo Carvalho de Melo
Date: Fri Nov 17 2017 - 15:32:50 EST
From: Wang Nan <wangnan0@xxxxxxxxxx>
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.
