/**
* 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)
