As I said, unless Dave has a strong point against it, I don't really
care if it lives in lib/ or not. It is infrastructure, but not
necessarily lib-like infrastructure.

Now, I have been thinking about this during the last hour, and as much
as all users are in fs/, putting it into mm/ would give us quite some
other advantage: namely, it has been already detected that we would like
to have, if possible, stronger ties between shrinkers, caches and the
underlying lists. We use a bunch of mm/ infrastructure, etc.

This is always something we can change if it really hurts, but right now
I am 51 % mm/ 49 % fs/
