From 1a271ebbfe33a44f61e02d35a2950ab00b32850b Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 9 Dec 2019 19:13:45 -0800 Subject: net/tipc: Replace rcu_swap_protected() with rcu_replace_pointer() This commit replaces the use of rcu_swap_protected() with the more intuitively appealing rcu_replace_pointer() as a step towards removing rcu_swap_protected().
