Cover letter [PATCH net-next 0/4] tun: Some bits required for tun's checkpoint-restore

Hi,

After taking a closer look on tun checkpoint-restore I've found several issues with the tun's API that make it impossible to dump and restore the state of tun device and attached tun-files.

The proposed API changes are all about extending the existing ioctl-based stuff. Patches fit today's net-next.
