I'm almost afraid to ask what you want to export to userspace for a workqueue that userspace would care about...
If you create a subsystem, the devices will show up under the virtual "bus" if you don't give them a parent, so this patch shouldn't be needed, unless you are abusing the driver model. What am I missing here?
