Here is another scenario I bumped onto - qdisc_watchdog_cancel() and
qdisc_restart() deadlock.

[...]
DEADLOCK!

Good catch.

Please try reverting commit 1936502d00ae6c2aa3931c42f6cf54afaba094f2,
that should fix it.

Ranko, did you get a chance to test this? I've attached the patch
since it doesn't revert cleanly ..

I have the commit reverted on my tree and have been testing it along
with the other changes to qdisc code I'm currently doing and it does
rectify the problem.
