So the big remaining ones for me are the /proc/<pid>/stack (stack pointers) and the /proc/net/* ones. I'm a bit disappointed that those haven't been fixed already and aren't even in this series.. Since I was the proponent of the whole "leaking_addresses" script model, I guess I can't complain when %p isn't then just made to hash everything, but it does feel like this has been dragging out a bit..
