zap_pte_range
do_swap_page	We enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults), and pte mapped but not yet locked.* We return with pte unmapped and unlocked.* We return with the mmap_sem locked or unlocked in the same cases
check_pte	heck_pte - check if @pvmw->page is mapped at the @pvmw->pte* page_vma_mapped_walk() found a place where @pvmw->page is potentially* mapped
page_vma_mapped_walk	page_vma_mapped_walk - check if @pvmw->page is mapped in @pvmw->vma at@pvmw->address@pvmw: pointer to struct page_vma_mapped_walk. page, vma, address and flags* must be set. pmd, pte and ptl must be NULL.* Returns true if the page is mapped in the vma
is_hugetlb_entry_migration
