330 The workqueue tracer provides some statistical information
331 about each cpu workqueue thread such as the number of the
332 works inserted and executed since their creation. It can help
333 to evaluate the amount of work each of them has to perform.
334 For example it can help a developer to decide whether he should
335 choose a per-cpu workqueue instead of a singlethreaded one.
