Al Viro 3278682123 make skb_copy_datagram_msg() et.al. preserve ->msg_iter on error
Fixes the mess observed in e.g. rsync over a noisy link we'd been
seeing since last Summer.  What happens is that we copy part of
a datagram before noticing a checksum mismatch.  Datagram will be
resent, all right, but we want the next try go into the same place,
not after it...

All this family of primitives (copy/checksum and copy a datagram
into destination) is "all or nothing" sort of interface - either
we get 0 (meaning that copy had been successful) or we get an
error (and no way to tell how much had been copied before we ran
into whatever error it had been).  Make all of them leave iterator
unadvanced in case of errors - all callers must be able to cope
with that (an error might've been caught before the iterator had
been advanced), it costs very little to arrange, it's safer for
callers and actually fixes at least one bug in said callers.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
