Subject: [PATCH 3/7] perf tests: Set evlist of test__sw_clock_freq() to !overwrite
Date: Mon, 13 Nov 2017 01:38:05 +0000 [thread overview]
Message-ID: <20171113013809.212417-4-wangnan0@huawei.com> (raw)
In-Reply-To: <20171113013809.212417-1-wangnan0@huawei.com>
Unsetting overwrite when calling perf_evlist__mmap is harmless. This commit
passes false to it, makes following commits eliminate the overwrite argument
easier.
