Luis R. Rodriguez 235586939d kmod: split out umh code into its own file
Patch series "kmod: few code cleanups to split out umh code"

The usermode helper has a provenance from the old usb code which first
required a usermode helper.  Eventually this was shoved into kmod.c and
the kernel's modprobe calls was converted over eventually to share the
same code.  Over time the list of usermode helpers in the kernel has grown
-- so kmod is just but one user of the API.

This series is a simple logical cleanup which acknowledges the code
evolution of the usermode helper and shoves the UMH API into its own
dedicated file.  This way users of the API can later just include umh.h
instead of kmod.h.

Note despite the diff state the first patch really is just a code shove,
no functional changes are done there.  I did use git format-patch -M to
generate the patch, but in the end the split was not enough for git to
consider it a rename hence the large diffstat.

I've put this through 0-day and it gives me their machine compilation
blessings with all tests as OK.

This patch (of 4):

There's a slew of usermode helper users and kmod is just one of them.
Split out the usermode helper code into its own file to keep the logic and
focus split up.

This change provides no functional changes.

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.
