-         * Disabling accounting is only relevant for some specific memcg
-         * internal allocations. Therefore we would initially not have such
-         * check here, since direct calls to the page allocator that are
-         * accounted to kmemcg (alloc_kmem_pages and friends) only happen
-         * outside memcg core. We are mostly concerned with cache allocations,
-         * and by having this test at memcg_kmem_get_cache, we are already able
-         * to relay the allocation to the root cache and bypass the memcg cache
-         * altogether.
-         *
-         * There is one exception, though: the SLUB allocator does not create
-         * large order caches, but rather service large kmallocs directly from
-         * the page allocator. Therefore, the following sequence when backed by
-         * the SLUB allocator:
-         *
-         *      memcg_stop_kmem_account();
-         *      kmalloc(<large_number>)
-         *      memcg_resume_kmem_account();
-         *
-         * would effectively ignore the fact that we should skip accounting,
-         * since it will drive us directly to this function without passing
-         * through the cache selector memcg_kmem_get_cache. Such large
-         * allocations are extremely rare but can happen, for instance, for the
-         * cache arrays. We bring this test here.
