Subject[RFC] hrtimer: About the warning message in hrtimer_interrupt()
Date
When the following warning message of hrtimer_interrupt() is output,
I often ignore it because I don't know what I should do.
-----
kernel/time/hrtimer.c
void hrtimer_interrupt(struct clock_event_device *dev)
{
:
pr_warn_once("hrtimer: interrupt took %llu ns\n",
ktime_to_ns(delta));
-----

What is the intention of this message?
What action should be required for this warning?
