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.

Ok then its restricted to the reclaimable slab caches already. The main
issue to sort out then is who is the "owner" of an inode/dentry (if
something like that exists). If you separate the objects into different
pages then the objects may be cleanly separated at the price of more
memory use.
