There is a global variable 'device_in_use' which is used to make sure only one instance is using /dev/kni device. If you were using LXC, you will find there is only one instance of KNI example could be run even different namespaces were created. In order to have /dev/kni used simultaneously in different namespaces, making all of global variables as per network namespace variables. With regard to single kernel thread mode, there will be one kernel thread for each of network namespace.
