Nico Pache 2fd570c1d8 selftests/mm: dont fail testsuite due to a lack of hugepages 
Patch series "selftests/mm: Improve Hugepage Test Handling in MM
Selftests", v2.

This series addresses issues related to hugepage requirements in the MM
selftests, ensuring tests are skipped rather than failing when the
necessary hugepage count is not met.

This adjustment allows for a more graceful handling for systems with
insufficient hugepages, preventing unnecessary test failures and improving
the overall robustness of the test suite.


This patch (of 3):

On systems that have large core counts and large page sizes, but limited
memory, the userfaultfd test hugepage requirement is too large.

Exiting early due to missing one test's requirements is a rather
aggressive strategy, and prevents a lot of other tests from running. 
Remove the early exit to prevent 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 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.
