Use the maple tree's advanced API and a maple state to walk the tree for the entry at the address of the next vma, then use the maple state to walk back one entry to find the previous entry. Add kernel documentation comments for this API. Link: https://lkml.kernel.org/r/20220906194824.2110408-13-Liam.Howlett@oracle.com Signed-off-by: Liam R.

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.
