Subject: [PATCH 15/19] perf tools: fix perf_evlist__mmap comments
Date: Fri, 18 Oct 2013 15:29:12 +0300	[thread overview]
Message-ID: <1382099356-4918-16-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1382099356-4918-1-git-send-email-adrian.hunter@intel.com>

Put the comments into the correct kernel-doc format and
correct reference to perf_evlist__read_on_cpu() which
should be perf_evlist__mmap_read().
