htb_destroy can either be called by qdisc_destroy or when a brand

the qdisc has never been used.
In the first case, as you have seen from my previous email, the
entire branch containing the HTB qdisc (that is, either the HTB
qdisc itself if it's being deleted directly, or the branch stemming
from its ancestor that's being deleted) must no longer have any
references to it at all apart from this thread of execution.
As such we can do whatever we want with it, including freeing it.
Cheers,
