DESCRIPTION

16       Forces execution of the workqueue and blocks until its completion. This
17       is typically used in driver shutdown handlers.
18
19       We sleep until all works which were queued on entry have been handled,
20       but we are not livelocked by new incoming ones.
21
22       This function used to run the workqueues itself. Now we just wait for
23       the helper threads to do it.
