Add test to assert that we have now allowed merging of VMAs when KSM merging-by-default has been set by prctl(PR_SET_MEMORY_MERGE, ...). We simply perform a trivial mapping of adjacent VMAs expecting a merge, however prior to recent changes implementing this mode earlier than before, these merges would not have succeeded. Assert that we have fixed this!

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 reStructuredText 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.
