Subject: arc: copy_thread(): rename 'arg' argument to 'kthread_arg'
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=18e1d1b115f79ab1f9137f2b4c72f87c218a5fb9;p=linux-beck.git

arc: copy_thread(): rename 'arg' argument to 'kthread_arg'

The 'arg' argument to copy_thread() is only ever used when forking a new
kernel thread. Hence, rename it to 'kthread_arg' for clarity.
