[PATCH mm-new 0/2] mm/khugepaged: refactor and merge PTE scanning logic

[Lance Yang]

Hi all,

This series cleans up the almost-duplicated PTE scanning logic in the
collapse path.

The first one is a preparatory step that refactors both loops to use
a single if-else-if-else-if chain for checking disjoint PTEs.

The second one then extracts the common logic into a shared helper.

Thanks,
Lance
