Merge branch 'for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq 

Pull workqueue updates from Tejun Heo:
 "Workqueue now prints debug information at the end of sysrq-t which
  should be helpful when tracking down suspected workqueue stalls.  It
  only prints out the ones with something currently going on so it
  shouldn't add much output in most cases"

* 'for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq:
  workqueue: Reorder sysfs code
  percpu: Fix trivial typos in comments
  workqueue: dump workqueues on sysrq-t
  workqueue: keep track of the flushing task and pool manager
  workqueue: make the workqueues list RCU walkable
