Not sure it's the best method, how about a dedicated f_op to do this?
So like a get_socket operation? That would simplify this a lot,
certainly (we wouldn't need to move private_data around in the tu

Instead of -1 with EAGAIN, read on a O_NONBLOCK tun fd will return 0. This
fixes this by properly returning the error code from __skb_recv_datagram.

Currently the "is-socket" test for a file compares the ops table pointer,
which is static and local to the socket.c. Instead, this adds a flag for
private_data_is_socket. This is an exceptionally long commit message for a
two-line patch.

By setting private_data to a socket and private_data_is_socket to true, we
can use the socket syscalls. We also can't just blindly use private_data
anymore, so there's a __tun_file_get function that returns the container_of
private_data appropriately.

There is an underlying socket object in struct tun that isn't accessible,
so if you try to do a recvmmsg on a tun file descriptor you'll get an
error. This small patchset allows external file objects to claim socket
status and enables it for tun_files.

Well
e right way to do
