Subject: [PATCH 3/3] perf/core: enabling mapping of the stop filters
Date: Fri, 15 Jul 2016 16:25:41 -0600	[thread overview]
Message-ID: <1468621541-31024-4-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1468621541-31024-1-git-send-email-mathieu.poirier@linaro.org>

At this time function perf_addr_filter_needs_mmap() will _not_
return true on a user space 'stop' filter.  But stop filters
needs exactly the same kind of mapping that range and start
filters get.
