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