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.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
