Subject: [PATCH 17/19] perf tools: Only set filter for tracepoints events
Date: Fri, 26 Feb 2016 20:18:29 -0300 [thread overview]
Message-ID: <1456528711-13793-18-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1456528711-13793-1-git-send-email-acme@kernel.org>
From: Wang Nan <wangnan0@huawei.com>
perf_evlist__set_filter() tries to set filter to every evsel linked in
the evlist. However, since filters can only be applied to tracepoints,
checking type of evsel before calling perf_evsel__set_filter() would be
better.
