Perhaps we've been operating under some incorrect assumptions then. If the
current patch series doesn't actually touch anonymous pages - the patch series
does touch code in e.g. mm/swap.c, but looking closer it might just be due to
the (mis)organization of the current code - maybe there aren't any real
objections left?
