Merge branch 'sch_cake-leaf-qdisc-fixes'

Toke Høiland-Jørgensen says:

====================
sched: Fix qdisc interactions exposed by using sch_cake as a leaf qdisc

This series fixes a couple of issues exposed by running sch_cake as a
leaf qdisc in an HFSC tree, which were discovered and reported by Pete
Heist. The interaction between CAKE's GSO splitting and the parent
qdisc's notion of its own queue length could cause queue stalls. While
investigating the report, I also noticed that several qdiscs would
dereference the skb pointer after dequeue, which is potentially
problematic since the GSO splitting code also frees the original skb.

See the individual patches in the series for details.
