Sure... I guess we could kick that from either direct reclaim or from
kswapd. But, then we're basically back to the places where
shrink_slab() is called.
I think that means that we think it's preferable to integrate this more
directly in the VM instead of sticking it off in the corner of tmpfs
only, or pretending it's a slab.
Dunno... The slab shrinker one isn't looking _so_ bad at the moment.
