- * This is the main placeholder for memcg-related information in kmem caches.
- * Both the root cache and the child caches will have it. For the root cache,
- * this will hold a dynamically allocated array large enough to hold
- * information about the currently limited memcgs in the system. To allow the
- * array to be accessed without taking any locks, on relocation we free the old
- * version only after a grace period.
- *
- * Root and child caches hold different metadata.
- *
- * @root_cache: Common to root and child caches.  NULL for root, pointer to
- *              the root cache for children.
- *
- * The following fields are specific to root caches.
- *
- * @memcg_caches: kmemcg ID indexed table of child caches.  This table is
- *              used to index child cachces during allocation and cleared
- *              early during shutdown.
- *
- * @root_caches_node: List node for slab_root_caches list.
- *
- * @children:   List of all child caches.  While the child caches are also
- *              reachable through @memcg_caches, a child cache remains on
- *              this list until it is actually destroyed.
- *
- * The following fields are specific to child caches.
- *
- * @memcg:      Pointer to the memcg this cache belongs to.
- *
- * @children_node: List node for @root_cache->children list.
- *
- * @kmem_caches_node: List node for @memcg->kmem_caches list.
