What is filter chains sharing here? Sounds like a new feature you are trying to hide? How could it be possibly shared among qdisc's when they are still stored in a per-qdisc pointer? Look at tc actions, they can be shared because they are physically stored in a per-netns hashtable, filters can just refer them with indexes.
