Subject: [PATCH 08/13] perf record: Add struct switch_output
Date: Wed, 11 Jan 2017 17:22:06 -0300	[thread overview]
Message-ID: <20170111202211.32137-9-acme@kernel.org> (raw)
In-Reply-To: <20170111202211.32137-1-acme@kernel.org>

From: Jiri Olsa <jolsa@kernel.org>

Next patches will add more --switch-output option arguments,
so preparing the data holder.
