/* Locking scheme -
* The shared resource which needs to be protected is realdev->rx_handler_data.
* For the writer path, this is using rtnl_lock(). The writer paths are
* rmnet_newlink(), rmnet_dellink() and rmnet_force_unassociate_device(). These
* paths are already called with rtnl_lock() acquired in. There is also an
* ASSERT_RTNL() to ensure that we are calling with rtnl acquired. For
* dereference here, we will need to use rtnl_dereference(). Dev list writing
* needs to happen with rtnl_lock() acquired for netdev_master_upper_dev_link().
* For the reader path, the real_dev->rx_handler_data is called in the TX / RX
* path. We only need rcu_read_lock() for these scenarios. In these cases,
* the rcu_read_lock() is held in __dev_queue_xmit() and
* netif_receive_skb_internal(), so readers need to use rcu_dereference_rtnl()
* to get the relevant information. For dev list reading, we again acquire
* rcu_read_lock() in rmnet_dellink() for netdev_master_upper_dev_get_rcu().
* We also use unregister_netdevice_many() to free all rmnet devices in
* rmnet_force_unassociate_device() so we dont lose the rtnl_lock() and free in
* same context.
