Subject: [PATCH tip/core/rcu 17/20] doc: Make listing in RCU perf/scale requirements use rcu_assign_pointer()
Date: Sun, 11 Nov 2018 11:56:42 -0800	[thread overview]
Message-ID: <20181111195645.9205-17-paulmck@linux.ibm.com> (raw)
In-Reply-To: <20181111195619.GA6958@linux.ibm.com>

From: "Joel Fernandes (Google)" <joel@joelfernandes.org>

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.
