Unlike the existing tests, this new test will create a memfd (backed by hugetlb) and pin the folios in it (a small subset) before writing/ populating it with data. This is a valid use-case that invokes the memfd_alloc_folio() kernel API and is expected to work unless there aren't enough hugetlb folios to satisfy the allocation needs.

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.
