With this patch, I get no lockdep warnings, but the machine locks up completely.
I hooked up a serial console, and found this..

BUG: warning at net/sched/sch_htb.c:395/htb_safe_rb_erase()

Call Trace:

I found the reason for this, it was an unrelated bug. I've attached
the latest version of the locking fixes and the fix for the HTB bug.
Can you please try again?

Although the HTB bug is post-2.6.18, the other issue has been
around for a long time.

Thus I'll need to submit the second patch to -stable, but I want
it to cook in Linus's tree for a few days before I do that.

Thanks.
