macvtap_device_event(NETDEV_UNREGISTER) should check vlan->minor to determine if it is being invoked in the context of a macvtap_newlink that failed, for example in this code sequence: macvtap_newlink macvlan_common_newlink register_netdevice call_netdevice_notifiers(NETDEV_REGISTER, dev) macvtap_device_event(NETDEV_REGISTER) <fail here, vlan->minor = 0> rollback_registered(dev); rollback_registered_many call_netdevice_notifiers(NETDEV_UNREGISTER, dev); macvtap_device_event(NETDEV_UNREGISTER) <nothing to clean up here> Signed-off-by:
