[PATCH v2 0/7] selftests/mm: Fix false positives and skip unsupported tests

[Aboorva Devarajan]

Hi all,

This patch series addresses false positives in the generic mm selftests
and skips tests that cannot run correctly due to missing features or system
limitations.

---

v1: https://lore.kernel.org/all/20250616160632.35250-1-aboorvad@xxxxxxxxxxxxx/

Changes in v2:

   - Rebased onto the mm-new branch, top commit of the base is 3b4a8ad89f7e ("mm: add zblock allocator").
   - Split some patches for clarity.
   - Updated virtual_address_range test to support testing 4PB VA on PPC64.
   - Added proper Fixes: tags.
   - Included a patch to skip a failing userfaultfd test when unsupported,
     instead of reporting a failure.

Please let us know if you have any further comments.

Thanks,
Aboorva
