Hello,
I find a scenario may cause deadlock of rtnl_lock as follows:
1. CPU1 add rtnl_lock and wait kworker finished.
CPU1 add rtnl_lock before call unregister_netdevice_queue() and
then wait sport->work(function srpt_refresh_port_work) finished
in srpt_remove_one().
This is an old kernel, this issue has been fixed
