[PATCH v3 0/2] selftests/mm: run the XFS-backed THP tests when xfs is a module

[Qiliang Yuan]

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.

V2 -> V3:
- Match xfs as a whole word so that selinuxfs and vxfs do not count
  (Jose A. Perez de Azpillaga)
- Rebase onto 6593a15af108 ("selftests/mm: skip khugepaged file tests
  if mkfs.xfs is unavailable")

V1 -> V2:
- Add load_module() and unload what the script loaded on exit (Zi Yan)
- Unload xfs again after the run (Zi Yan)
- Rebase onto mainline
