it'd seem we need some kind of state management here to figure out good
intervals of when to call mark_page_accessed() *again* for this page. E.g.
despite non-changing access patterns you could still call mark_page_accessed(

every 32 calls or so to avoid expiry, but this would need extra helper
variables.
What if you did something like
if (jiffies%32) {...
(Possibly scaling it so the low-order bits change). No need to lock it, as
"right most of the time" is close enough.
Bad idea. That way you would only count page accesses if the
phase of the moon^Wjiffie is just right.
