net: treewide use of RCU_INIT_POINTER
rcu_assign_pointer(ptr, NULL) can be safely replaced by RCU_INIT_POINTER(ptr, NULL) (old rcu_assign_pointer() macro was testing the NULL value and could omit the smp_wmb(), but this had to be removed because of compiler warnings) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
