They should indeed. Not urgent but it will optimize the vm (as in virtual memory) cpu load a bit.

That's my point, current implementation of PageKsm don't seem to last long, and if we keep logic the same it'll likely happen soon that PageKsm != PageAnon on a Ksm page. So I'd rather keep it different even now, given I doubt it's moving the needle anywhere in ksm code.
