From 36708b89e00951b004b4dd6c14181301e2e98354 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 9 Dec 2013 15:19:53 -0800 Subject: bonding: Use RCU_INIT_POINTER() for better overhead and for sparse Although rcu_assign_pointer() can be used to assign a constant NULL pointer, doing so gets you an unnecessary memory barrier and in some circumstances, sparse warnings. This commit therefore changes the rcu_assign_pointer() of NULL in __bond_release_one() to RCU_INIT_POINTER(). Signed-off-by: Paul E.
