Since this doesn't always show up, I don't mind to have the function
name shown explicitly there.  OTOH, what bothers me is that all those
messages have a short format "__func__: %d" while the values are
utterly different, depending on the function.  That can be confusing.
IMO, it'd be more user-friendly to indicate what values are presented,
too.
