Each process that belongs to a memcg triggers the creation of a new
child kmem cache.

From the PoV of the global system, what you'll see is something like:
dentry , dentry(2:memcg1), dentry(2:memcg2), etc.
No attempt is made to provide any view of those caches in a logically
grouped way - the global system can view them independently.
