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 from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
