====================
net: Finish up ->msg_control{,_user} split
Commit 1f466e1f15 ("net: cleanly handle kernel vs user buffers for
->msg_control") introduced the msg_control_user and
msg_control_is_user fields in struct msghdr, to ensure that user
pointers are represented as such. It also took care of converting most
users of struct msghdr::msg_control where user pointers are involved. It
did however miss a number of cases, and some code using msg_control
inappropriately has also appeared in the meantime.
This series is attempting to complete the split, by eliminating the
remaining cases where msg_control is used when in fact a user
pointer is stored in the union (patch 1).
It also addresses a couple of issues with msg_control_is_user: one where
it is not updated as it should (patch 2), and one where it is not
initialised (patch 3).
v1..v2:
* Split out the msg_control_is_user fixes into separate patches.

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.
