The hugetlbfs and THP support in the walk_page_range() code was mostly an afterthought. We also _tried_ to have the pagewalk code be concerned only with page tables and *NOT* VMAs. We lost that battle since 80% of the page walkers just pass the VMA along anyway. This does a few cleanups and adds a new flavor of walker which can be stupid^Wsimple and not have to be explicitly taught about THP. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
