>From c9bba34243a86fb3ac82d1bdd0ce4bf796b79559 Mon Sep 17 00:00:00 2001
From: Tejun Heo <tj@xxxxxxxxxx>
Date: Thu, 19 Jul 2012 13:52:53 -0700
Make the following two non-functional changes.
* Separate out insert_kthread_work() from queue_kthread_work().
* Relocate struct kthread_flush_work and kthread_flush_work_fn()
definitions above flush_kthread_work().
