rcu: Remove obsolete comment from __call_rcu()
The __call_rcu() comment about opportunistically noting grace period beginnings and endings is obsolete. RCU still does such opportunistic noting, but in __call_rcu_core() rather than __call_rcu(), and there already is an appropriate comment in __call_rcu_core(). This commit therefore removes the obsolete comment. Reported-by: Michalis Kokologiannakis <mixaskok@gmail.com> Signed-off-by: Paul E.
