[PATCH tip/core/rcu 17/20] doc: Make listing in RCU perf/scale requirements use rcu_assign_pointer()
From: Paul E. McKenney
Date: Sun Nov 11 2018 - 14:57:00 EST
From: "Joel Fernandes (Google)" <joel@xxxxxxxxxxxxxxxxx>
The code listing under this section has a quick quiz that says line
19 uses rcu_access_pointer, but the code listing itself instead uses
rcu_dereference(). This commit therefore makes the code listing match
the quick quiz.
