Subject: [PATCH 10/32] cris/arch-v32: copy_thread(): rename 'arg' argument to 'kthread_arg'
Date: Fri, 13 Mar 2015 20:04:25 +0200 [thread overview]
Message-ID: <1426269888-25600-10-git-send-email-alexinbeijing@gmail.com> (raw)
In-Reply-To: <1426269888-25600-1-git-send-email-alexinbeijing@gmail.com>
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()).
