Oh and shouldn't this be inverted?

0 eagerness = we eat up all none PTE entries? Isn't that pretty eager? :P
10 eagerness = we aren't eager to eat up none PTE entries at all?

Or am I being dumb here?

For swappiness it's: 0 -> no swap (conservative)

So intuitively I assumed: 0 -> no pte_none (conservative)

You're the native speaker, so you tell me :)
