Oh, I didn't mean to use object-specific counting for all of them. Most resources don't have such common misaccounting problem. I mean, for stack, it doesn't exist by definition (other than cgroup migration). There's no reason to use anything other than first-use kmem based accounting for them. My point was that for particularly problematic ones like dentry/inode, it might be better to treat them differently.
Thanks.
