There's a notifier chain that then allows drivers (or subsystems) to be notified of the current requirements, the idea being that they can then limit their deepest power saving mode to one that still satisfies the userspace constraints. But yeah, it's not really worth worrying about until the code works :) -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
