- * mm_walk - callbacks for walk_page_range
- * @pud_entry: if set, called for each non-empty PUD (2nd-level) entry
- * this handler should only handle pud_trans_huge() puds.
- * the pmd_entry or pte_entry callbacks will be used for
- * regular PUDs.
- * @pmd_entry: if set, called for each non-empty PMD (3rd-level) entry
- * this handler is required to be able to handle
- * pmd_trans_huge() pmds. They may simply choose to
- * split_huge_page() instead of handling it explicitly.
- * @pte_entry: if set, called for each non-empty PTE (4th-level) entry
- * @pte_hole: if set, called for each hole at all levels
- * @hugetlb_entry: if set, called for each hugetlb entry
- * @test_walk: caller specific callback function to determine whether
- * we walk over the current vma or not. Returning 0
- * value means "do page table walk over the current vma,"
- * and a negative one means "abort current page table walk
- * right now." 1 means "skip the current vma."
- * @mm: mm_struct representing the target process of page table walk
- * @vma: vma currently walked (NULL if walking outside vmas)
- * @private: private data for callbacks' usage
- *
- * (see the comment on walk_page_range() for more details)
