Subject: perf tests: Set evlist of test__basic_mmap() to !overwrite
X-Git-Tag: v4.16-rc1~166^2~18^2~30
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=301d724aa19add1c0cf3ec8cad0d10151d30393f;p=linux.git

perf tests: Set evlist of test__basic_mmap() to !overwrite

In this test, a large ring buffer is required so all events can feed
into, so overwrite or not is meaningless.

Change to !overwrite so following commits can remove this argument.
