What happens if a different processor updates the stucture before before the one scheduled to be deleted is deleted. It must keep a queue of these sturctures to delete, right? RCU seems like a nice and simple algorithm.

Yep, RCU maintains a per-CPU queue of callbacks registered by call_rcu(), which in this case would be equivalent to a per-CPU queue of items to be deleted.
