Ok it's very unlikely -- the timer would have to rearm itself and the fire the exact same moment we try to del_timer() it, so it's still running when we return, and then we'd have to unload the module quickly enough to invalidate that code that's running there ... it's a bit of a stretch, but not completely impossible. johannes -- 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
