- u64 hrtimer_forward_now(struct hrtimer * timer, ktime_t interval);
- hrtimer to forward
- the interval to forward
Forward the timer expiry so it will expire after the current time of the hrtimer clock base. Returns the number of overruns.
Can be safely called from the callback function of timer. If called from other contexts timer must neither be enqueued nor running the callback and the caller needs to take care of serialization.
This only updates the timer expiry value and does not requeue the timer.
