But after core-1\ndevice_unregister, put_device and before doing kfree, the core-2 may\nget_device. Then:\n1. After core-1 kfree idev, the core-2 will do use-after-free for idev.\n2. When core-2 do uio_release and put_device, the idev will be double\n freed.\n\nTo address this issue, we can get idev atomic & inc idev reference with\nminor_lock."
