   234	The ``PAGEMAP_SCAN`` IOCTL on the pagemap file can be used to get or optionally
   235	clear the info about page table entries. The following operations are supported
   236	in this IOCTL:
   237	- Get the information if the pages have been written to (``PAGE_IS_WRITTEN``),
 > 238	  file mapped (``PAGE_IS_FILE``), present (``PAGE_IS_PRESENT``), swapped
   239	  (``PAGE_IS_SWAPPED``) or page has pfn zero (``PAGE_IS_PFNZERO``).
 > 240	- Find pages which have been written to and/or write protect the pages atomically
   241	  (atomic ``PM_SCAN_OP_GET + PM_SCAN_OP_WP``)
