Maybe we can use better terms which reflect the single layer structure better? And, again, in general, please add some comments. If someone tries to understand this for the first time and takes a look at mem_cgroup_cache_params, there's almost nothing to guide that person. What's the struct for? What does each field do? What are the synchronization rules? > @@ -626,6 +630,9 @@ void memcg_release_cache(struct kmem_cache *cachep) > { > if (cachep->memcg_params.id != -1) > ida_simple_remove(&cache_types, cachep->memcg_params.id); > + else > + list_del(&cachep->memcg_params.sibling_list); > + list_del_init() please.
