Vlastimil Babka 097d70c627 mm/mmap/vma_merge: use the proper vma pointer in case 3
In case 3 we we use 'next' for everything but vma_pgoff.  So use 'next'
for that as well, instead of 'mid', for consistency.  Then in case 8 we
have to use 'mid' explicitly, which should also make the intent more
obvious.

Adjust the diagram for cases 1-3 in the comment to match the code - we are
using 'next' for case 3 so mark the range with XXXX instead of NNNN.  For
case 2 that's a no-op as the code doesn't touch 'next' or 'mid'.  For case
1 it's now wrong but that will be fixed next.

No functional change.

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.
