Subject: [PATCH 5/7] perf evlist: Do not pass struct record_opts to perf_evlist__prepare_workload()
Date: Mon, 11 Mar 2013 16:43:16 +0900
Message-ID: <1362987798-24969-5-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1362987798-24969-1-git-send-email-namhyung@kernel.org>

From: Namhyung Kim <namhyung.kim@lge.com>

Since it's only used for checking ->pipe_output, we can pass the
result directly.

Now the perf_evlist__prepare_workload() don't have a dependency of
struct perf_record_opts, it can be called from other places like perf
stat.
