The only user of devmap PTEs is FS DAX, and khugepaged should not be scanning these VMAs. This is checked by calling hugepage_vma_check. Therefore khugepaged should never encounter a devmap PTE.

I will likely remove it as the whole thing gets deleted when pXX_devmap is removed.
Yes, doesn't make sense for this patch to exist if it would go upstream along with the next patch that removes that completely.
