unregister_netdevice: waiting for lo to become free
Status in linux package in Ubuntu:
In Progress
Bug description:
This is a "continuation" of bug 1403152, as that bug has been marked

[Impact]
When shutting down and starting containers the container network
namespace may experience a dst reference counting leak which results
in this message repeated in the logs:
unregister_netdevice: waiting for lo to become free. Usage count =
1
This can cause issues when trying to create net network namespace and
thus block a user from creating new containers.
[Test Case]
