documentation: Document call_rcu() safety mechanisms and limitations The call_rcu() family of primitives will take action to accelerate grace periods when the number of callbacks pending on a given CPU becomes excessive. Although this safety mechanism can be useful, it is no substitute for users of call_rcu() having rate-limit controls in place. This commit adds this nuance to the documentation.
