From c0eaf15cd5d39e79feb81a122975df0bb5a1c106 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 23 Sep 2019 15:26:28 -0700 Subject: drivers/scsi: 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().
