Thanks for the patch. I tested your patch and it is working fine. I do
not notice the rcu stall warnings anymore. I have just updated the
formatting of brackets. Please check and apply

The intention of me including the callstack was to help anyone notice
this commit while searching using the prints from the callstack. I have
removed it if it is creating noise.

r are synchronized using tick_broadcast_lock. So there is no need
for the existing try to cancel logic. All this can be removed which will
eliminate the race condition as well.
