- * Generic net pointers are to be used by modules to put some private
- * stuff on the struct net without explicit struct net modification
- *
- * The rules are simple:
- * 1. set pernet_operations->id. After register_pernet_device you
- * will have the id of your private pointer.
- * 2. set pernet_operations->size to have the code allocate and free
- * a private structure pointed to from struct net.
- * 3. do not change this pointer while the net is alive;
- * 4. do not try to have any private reference on the net_generic object.
- *
- * After accomplishing all of the above, the private pointer can be
- * accessed with the net_generic() call.
