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
