The right value (if you're looking for consistency with Linux 2.4)
is the number of currently resident "library" pages: and we don't
know that number - we can't even define what a library is.

We could add some code to make it show the same bogus number as
we show somewhere else, but it has said 0 ever since 2.5.37: so
I don't think it's worth a line of code myself, but bow to others.

What does alarm me is that you think this is fit for -stable!
