HRTIMER_FORWARD_NOW(9) Driver Basics HRTIMER_FORWARD_NOW(9)

NAME

hrtimer_forward_now - forward the timer expiry so it expires after now

SYNOPSIS

u64 hrtimer_forward_now(struct hrtimer * timer, ktime_t interval);

ARGUMENTS

timer
hrtimer to forward
interval
the interval to forward

DESCRIPTION

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.

NOTE

This only updates the timer expiry value and does not requeue the timer.
