Another possible example might be the skb data, which are just kmalloc

not want to account them a second time.
How so?
struct sk_buff *__alloc_skb(unsigned int size, gfp_t gfp_mask,
int fclone, int node)
{
[ ... ]
cache = fclone ? skbuff_fclone_cache : skbuff_head_cache;
/* Get the HEAD */
skb = kmem_cache_alloc_node(cache, gfp_mask& ~__GFP_DMA, node);
Just a few lines below:
data = kmalloc_node_track_caller(size, gfp_mask, node);

Can't we just make sure those come from the root cgroup's slabs?
Then we need no flag.
