The library call is there. It's the kernel which doesn't have the
functionality: the swapper assumes that all swappable pages are
private.
The swap cache code in 2.1 makes this much easier to fix, but in the
end it's going to be a 2.3 job. In all likelihood 2.2 will not
support shared anonymous mappings.
