That is not what the kernel does, in general. We assume that if he wants
that memory and we can serve it, we should. Also, not all kernel memory
is unreclaimable. We can shrink the slabs, for instance. Ying Han
claims she has patches for that already...

Are those patches somewhere around?

You can already shrink the reclaimable slabs (dentries / inodes) via
calls to the subsystem specific shrinkers. Did Ying Han do anything to
go beyond that?

The Google shrinker patches enhance prune_dcache_sb() to limit dentry
pressure to a specific memcg.
