Subject: [PATCH] sched: loadavg: delete useless param ticks for calc_global_load
Date:   Tue, 28 Jul 2020 16:58:07 +0800
Message-Id: <20200728085809.60132-1-wenhu.wang@vivo.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The only parameter "unsigned long ticks" for calc_global_load is
never used inside the function definition. Delete it now.
