Subject: [PATCH 02/13] proc: apply seq_puts() whenever possible
Date:   Tue, 28 Aug 2018 02:14:52 +0300
Message-Id: <20180827231503.26899-2-adobriyan@gmail.com>
In-Reply-To: <20180827231503.26899-1-adobriyan@gmail.com>
References: <20180827231503.26899-1-adobriyan@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

seq_puts() is faster than seq_printf() because it doesn't search for
format specifiers.
