From a9b3cd7f323b2e57593e7215362a7b02fc933e3a Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 1 Aug 2011 16:19:00 +0000 Subject: rcu: convert uses of rcu_assign_pointer(x, NULL) to RCU_INIT_POINTER When assigning a NULL value to an RCU protected pointer, no barrier is needed. The rcu_assign_pointer, used to handle that but will soon change to not handle the special case. Convert all rcu_assign_pointer of NULL value. //smpl @@ expression P; @@ - rcu_assign_pointer(P, NULL) + RCU_INIT_POINTER(P, NULL) // Signed-off-by: Stephen Hemminger Acked-by: Paul E.
