The linux-next integration testing tree

Previously, vma was an uninitialised variable which was only definitely assigned as a result of the logic covering all possible input cases - for it to have remained uninitialised, prev would have to be NULL, and next would _have_ to be mergeable. The value of res defaults to NULL, so we can neatly eliminate the assignment to res and vma in the if (prev) block and ensure that both res and vma are both explicitly assigned, by just setting both to prev. In addition we add an explanation as to under what circumstances both might change, and since we absolutely do rely on addr == curr->vm_start should curr exist, assert that this is the case.

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.
