From: Olliver Schinagl <oliver@schinagl.nl>
When using a hrtimer for repeating periodic ticks, hrtimer_forward_now() is often used. Quite possibly the timer loop is thus probably fully controlled by hrtimer_forward_now() and we don't really care when the timer is started. With hrtimer_start() we need to define exactly when a event has to start. By introducing hrtimer_start_now() we do the same as what hrtimer_forward_now() does, start as soon as possible and get into the timer loop.
