Indeed, Uwe still needs to respond to how he wants to handle that. I still prefer making it %pE, both because it's easier to convert integers to ERR_PTRs than having to worry about the type of PTR_ERR() being long and not int, and because alphanumerics after %p have been ignored for a long time (10 years?) whether or not those characters have been recognized as a %p extension, so nobody relies on %pE putting an E after the %p output. It also keeps the non-standard extensions in the same "namespace", so to speak. Oh, 'E' is taken, well, make it 'e' then. Rasmus
