Subject: [PATCH 01/53] workqueue: Introduce the create*_workqueue2() macros
A common pattern in the Linux kernel is that sprintf(), snprintf() or
kasprintf() is used to format the workqueue name that is passed to
create_workqueue(), create_freezable_workqueue() or
create_singlethread_workqueue(). Prepare for simplifying such code by
introducing the create*_workqueue2() macros that accept a printf-style
format string and argument list. A later patch will remove the
create*_workqueue() macros and will rename the create*_workqueue2()
macros into create*_workqueue().
