[PATCH V2 0/5] mm/khugepaged: cleanups and scan limit fix

[Shivank Garg <shivankg@amd.com>]

This series contains several cleanups for mm/khugepaged.c to improve code
readability and type safety, and one functional fix to ensure
khugepaged_scan_mm_slot() correctly accounts for small VMAs towards
scan limit.

Thanks,

v2:
- Added a fix for small VMAs not being counted in the scan limit (Wei)
- Updated 'progress' to 'unsigned int' to match types
- Update return types of internal functions to use enum scan_result (Zi)
- Add void wrapper collapse_pte_mapped_thp() for external callers to avoid
  exposing internal enum (David)
