It's a pretty dumb thing to do anyway.Fragile, yes; dumb, no. At least not from the point-of-view of the documentation and what the workqueue actually did. But obviously from your reaction, unintentional design.
Well, maybe dumb is too strong a word but these types of edge case interfaces tend to cause subtle issues over time while being marginally useful at best. Sure it helps a couple odd users to write slightly less code, but that's such a marginal gain compared to the fragility it adds by being another one-off thing. So, yeah, it's a silly thing to include in an interface as widely use as workqueue and it's more of a historical remanant than anything else at this point. Thanks. -- tejun
