datagram: consolidate datagram copy to iter helpers
skb_copy_datagram_iter and skb_copy_and_csum_datagram are essentialy the same but with a couple of differences: The first is the copy operation used which either a simple copy or a csum_and_copy, and the second are the behavior on the "short copy" path where simply copy needs to return the number of bytes successfully copied while csum_and_copy needs to fault immediately as the checksum is partial. Introduce __skb_datagram_iter that additionally accepts: 1. copy operation function pointer 2. private data that goes with the copy operation 3. fault_short flag to indicate the action on short copy Suggested-by: David S.
