+ 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!
