From 18e1d1b115f79ab1f9137f2b4c72f87c218a5fb9 Mon Sep 17 00:00:00 2001 From: Alex Dowad Date: Fri, 13 Mar 2015 20:04:18 +0200 Subject: [PATCH] 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.
