Merge branch 'for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue updates from Tejun Heo:
"Mostly patches to initialize workqueue subsystem earlier and get rid
of keventd_up().
The patches were headed for the last merge cycle but got delayed due
to a bug found late minute, which is fixed now.
Also, to help debugging, destroy_workqueue() is more chatty now on a
sanity check failure."
