Subject: [PATCH 41/73] libperf: Add perf_mmap__mmap_len function
Date: Fri, 13 Sep 2019 15:23:23 +0200 [thread overview]
Message-ID: <20190913132355.21634-42-jolsa@kernel.org> (raw)
In-Reply-To: <20190913132355.21634-1-jolsa@kernel.org>
Move perf_mmap__mmap_len function under libperf,
it will be used in following patches. And rename
the existing perf's function to mmap__mmap_len.
