would you share some numbers ?

a little bit. Yeah. It added about 600ms of time spent on musb's probe
when we were using blocking notifier for charger detection. When we
moved to atomic notifier, that was solved. Anyway, you can never be sure
when that will be scheduled and if cpu is really busy, it might pose a
great deal.
