Patch series "New selftest for mm", v2. This is a simple test case that reproduces an mm problem[1], where a page fault races with madvise(), and it is not trivial to reproduce and debug. This test-case aims to avoid such race problems from happening again, impacting workloads that leverages external allocators, such as tcmalloc, jemalloc, etc. [1] https://lore.kernel.org/all/20231001005659.2185316-1-riel@surriel.com/#r This patch (of 2): get_free_hugepages() is helpful for other hugepage tests. Export it to the common file (vm_util.c) to be reused.

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.
