+        help
+          This option makes it possible to send different netlink messages
+          to tasks depending on whether the task is a compat task or not. To
+          achieve this, you need to set skb_shinfo(skb)->frag_list to the
+          compat skb before sending the skb, the netlink code will sort out
+          which message to actually pass to the task.
+
+          Newly written code should NEVER need this option but do
+          compat-independent messages instead!
