Subject: [PATCH] include: replace tsk to task in linux/sched/signal.h
Date:   Thu, 29 Nov 2018 10:05:47 -0800
Message-Id: <20181129180547.15976-1-avagin@gmail.com>
In-Reply-To: <20181121181650.8d2d6abcf83b9defb7195cd3@linux-foundation.org>
References: <20181121181650.8d2d6abcf83b9defb7195cd3@linux-foundation.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This file uses "task" 85 times and "tsk" 25 times. It should be better to
choose one of these variants.
