OK, thanks. We need to reap those pages up-front rather than waiting
for them to come to the tail of the LRU.

What on earth is going on with kmem_cache_reap? Am I missing
something, or is that thing 700% overdesigned? Why not just
free the darn pages in kmem_cache_free_one()? Maybe hang onto
a few pages for cache warmth, but heck.
