Subject: [PATCH 08/36] perf tools: Use perf_mmap way to detect aux mmap
Date: Mon, 7 Oct 2019 14:53:16 +0200 [thread overview]
Message-ID: <20191007125344.14268-9-jolsa@kernel.org> (raw)
In-Reply-To: <20191007125344.14268-1-jolsa@kernel.org>
We will move this code to libperf shortly, so we need to free it of
'struct auxtrace_mmap' usage, because it won't be available in libperf
(for now).
The perf_event_mmap_page::aux_size is set when the aux mmap is mapped,
so the check is equivalent.
