Subject: [PATCH 12/32] hexagon: copy_thread(): rename 'arg' argument to 'kthread_arg' Date: Fri, 13 Mar 2015 20:14:35 +0200 Message-Id: <1426270496-26362-2-git-send-email-alexinbeijing@gmail.com> X-Mailer: git-send-email 2.0.0.GIT In-Reply-To: <1426270496-26362-1-git-send-email-alexinbeijing@gmail.com> References: <1426270496-26362-1-git-send-email-alexinbeijing@gmail.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org The 'arg' argument to copy_thread() is only ever used when forking a new kernel thread. Hence, rename it to 'kthread_arg' for clarity (and consistency with do_fork() and other arch-specific implementations of copy_thread()).
