Merge branch 'for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq

Pull workqueue updates from Tejun Heo:
 "Lai has been doing a lot of cleanups of workqueue and kthread_work.
  No significant behavior change.  Just a lot of cleanups all over the
  place.  Some are a bit invasive but overall nothing too dangerous"
