Sometimes you want timer-driven behaviour (how else are you going to draw animations?) and that's obviously going to generate wakeups. This is for the idle case, where the user is no longer sitting in front of the machine but you don't want to trigger a full system suspend. We either need every application that ever uses timer-driven behaviour to support setting its own timer slack on some sort of external policy decision, or we need a way to let the kernel force them to. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
