I need to avoid some fields is not 0 when the new workgroup is created (because work->nr_pages and work->vcnt == 0 usually after the previous workgroup is freed). But that is not obvious, it is promised by the current logic. In order to not introduce such a issue in the future, or there are some potential race (work->nr_pages and work->vcnt != 0 when the previous workgroup == 0), it need to be noticed to developpers as early as possible.
