Yes the old names are a giant mess. I am not sure the new ones are
that much better however.

Both are bad because the first suggests we are creating memcg and the second that
we are requesting a copy of memcg.

memcg_alloc_kmem_cache?

_copy suffix is a bit confusing. E.g. copy_mm and others either to
shallow or deep copy depending on the context. This one always creats a
deep copy. Also why it is imporatant to treat the created caches as
copies?

memcg_register_kmem_cache? It also allocates so this name is a bit
awkward as well.

> memcg_kmem_destroy_cache                memcg_destroy_kmem_cache_copy

memcg_unregister_kmem_cache to match the above?

> kmem_cache_destroy_memcg_children       kmem_cache_destroy_memcg_copies

_children suffix is really confusing because they have different meaning in
memcg and refer to children groups.

memcg_cleanup_kmem_chache_memcg_params? It doesn't have to live in the
kmem_cache namespace because it only does only memcg kmem specific
stuff.

memcg_register_cache_work?

memcg_register_cache_func?

> memcg_create_cache_enqueue              memcg_schedule_kmem_cache_copy

memcg_schedule_register_cache?
