- * 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. register the ops with register_pernet_gen_device to get the id
- * of your private pointer;
- * 2. call net_assign_generic() to put the private data on the struct
- * net (most preferably this should be done in the ->init callback
- * of the ops registered);
- * 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.
