rcu: convert uses of rcu_assign_pointer(x, NULL) to RCU_INIT_POINTER
Stephen Hemminger [Mon, 1 Aug 2011 16:19:00 +0000 (16:19 +0000)]
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)
