Subject: list_for_each_rcu() must die: networking
From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx>
All uses of list_for_each_rcu() can be profitably replaced by the
easier-to-use list_for_each_entry_rcu(). This patch makes this change for
networking, in preparation for removing the list_for_each_rcu() API entirely.
