Subject: [PATCH tip/core/rcu 19/21] netlink: Remove smp_read_barrier_depends() from comment
Date: Fri, 1 Dec 2017 11:51:14 -0800 [thread overview]
Message-ID: <1512157876-24665-19-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20171201195053.GA23494@linux.vnet.ibm.com>
Now that smp_read_barrier_depends() has been de-emphasized, the less
said about it, the better.
