Oh, I meant whether it's necessary to keep css_from_id() working (ie. doing successful lookups) between offline and release, because that's where lifetimes are coupled. IOW, if it's enough for cgroup to not recycle the ID until all css's are released && fail css_from_id() lookup after the css is offlined, I can make a five liner quick fix.
