Subject: [PATCH 02/19] perf stat: Split print_running() function
Date: Mon, 14 Nov 2022 15:02:10 -0800 [thread overview]
Message-ID: <20221114230227.1255976-3-namhyung@kernel.org> (raw)
In-Reply-To: <20221114230227.1255976-1-namhyung@kernel.org>
To make the code more obvious and hopefully simpler, factor out the
code for each output mode - stdio, CSV, JSON.
