[PATCH v2 0/2] selftests/mm: run the XFS-backed THP tests when xfs is a module

[Qiliang Yuan <odys.yuan@gmail.com>]

run_vmtests.sh only creates the XFS that "khugepaged all:file" and the
pagecache folio split cases of split_huge_page_test need when xfs is
already registered, so with xfs built as a module and not loaded yet
those tests are all skipped.

Patch 1 adds load_module(), which records the modules the script loads
and unloads them again before it exits, and moves hwpoison_inject over
to it. Patch 2 loads xfs through it.
