   can't we just change rss to count pages? 

This is what it does now.

   or are we worried about rss's over ~16 TB?

If we weren't, we could just use an atomic_t for this problem.
We can't.

This patch is the only currently available solution to this problem
which is in any way acceptable.

Later,
