If is taken rarely enough it will still be worth it. Otherwise it may be hard to know what operations need to invalidate the napi reference. It can very well be HW dependent, and then you end up adding a function for drivers to call to do the invalidation. Or we can decide that we only care about catastrophic events and only worry about a napi completely going away and not worry about configuration changes.(Polling the wrong queue will not kill you, it's just a waste of perfectly good CPU cycles.) ------------------------------------------------------------------------------ Everyone hates slow websites.
