New patch attached.



How do these child qdiscs get destroyed at all if you just
remove them from the lists they are on?  How will the rest
of destroy processing find them and clean them up?



The RCU-callback calls ops->destroy. The qdisc knows about it's inner
structure and destroys all classes and the inner qdiscs. dev->qdisc_list
is just a flat list containing all qdiscs of the tree for lookups.
