As I see it, page cache seems too persistant (it grows out of bounds)
when we age pages in it.

One wrong way of fixing it is to limit page cache size, IMNSHO.

I_my_NSHO, it's an awful way to fix it: adding yet another rule to the
VM is not progress, it's making things worse!

I tried the other way, to age page cache harder, and it looks like it
works very well. Patch is simple, so simple that I can't understand
nobody suggested (something like) it yet.

It has been suggested before, and that's why a lot of people have
reported great success by having page ageing removed: it essentially
lets pages age faster by limiting the number of ageing passes required
to remove a page (essentially this just reduces the age value down to
the page's single PG_referenced bit).

And yes, it should work fine.
