Actually I added the following code in patch 5/5:

+               if (!ipv6_addr_equal(&a->sin6.sin6_addr,
&b->sin6.sin6_addr))
+                       return false;
+               else if
(__ipv6_addr_needs_scope_id(__ipv6_addr_type(&a->sin6.sin6_addr)))
+                       return a->sin6.sin6_scope_id ==
b->sin6.sin6_scope_id;


but I should move it to this patch, otherwise it is hard for review.

Thanks!
