Subject: [PATCH 03/19] perf stat: Split print_noise_pct() function
Date: Mon, 14 Nov 2022 15:02:11 -0800 [thread overview]
Message-ID: <20221114230227.1255976-4-namhyung@kernel.org> (raw)
In-Reply-To: <20221114230227.1255976-1-namhyung@kernel.org>
Likewise, split print_noise_pct() for each output mode. Although it's
a tiny function, more logic will be added soon so it'd be better split
it and treat it in the same way.
