Subject: [PATCH v2 0/2] selftests/mm: split_huge_page_test: split_pte_mapped_thp improvements

One fix for occasional failures I found while testing and a bunch of
cleanups that should make that test easier to digest.

Tested on x86-64, the test seems to reliably pass.

Mostly a resend, because I accidentally disabled "ccover = true" in my
git config so people were only CCed on the cover letter.

v1 -> v2:
* "selftests/mm: split_huge_page_test: fix occasional is_backed_by_folio()
  wrong results"
 -> Fixup missing ")" in patch description

David Hildenbrand (2):
  selftests/mm: split_huge_page_test: fix occasional
    is_backed_by_folio() wrong results
  selftests/mm: split_huge_page_test: cleanups for split_pte_mapped_thp
    test
