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
