net: skb_copy_datagram_from_iovec()
There's an skb_copy_datagram_iovec() to copy out of a paged skb, but nothing the other way around (because we don't do that). We want to allocate big skbs in tun.c, so let's add the function. It's a carbon copy of skb_copy_datagram_iovec() with enough changes to be annoying. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: David S. Miller <davem@davemloft.net>
