Lines Matching full:pages

36    swap. Unmapped pages return a null PFN. This allows determining
37    precisely which pages are mapped (or in swap) and comparing mapped
38    pages between processes.
100     An order N block has 2^N physically contiguous pages, with the BUDDY flag
103     A compound page with order N consists of 2^N physically contiguous pages.
106     pages are hugeTLB pages (Documentation/admin-guide/mm/hugetlbpage.rst),
108     However in this interface, only huge/giga pages are made visible
119     Identical memory pages dynamically shared between one or more processes.
121     Contiguous pages which construct THP of any size and mapped by any granularity.
158    not a candidate for LRU page reclaims, e.g. ramfs pages,
179 Page table entries for shared pages are cleared when the pages are zapped or
180 swapped out. This makes swapped out pages indistinguishable from never-allocated
190 lseek() can differentiate between accessed pages (present or swapped out) and
192 the pages are backed. For anonymous shared pages, the file can be found in
195 mincore() can differentiate between pages in memory (present, including swap
219 - Write-protect the pages. The ``PM_SCAN_WP_MATCHING`` is used to write-protect
220   the pages of interest. The ``PM_SCAN_CHECK_WPASYNC`` aborts the operation if
221   non-Async Write Protected pages are found. The ``PM_SCAN_WP_MATCHING`` can be
224   get and write protect the pages as well.
226 Following flags about pages are currently supported:
251  6. The optional maximum requested pages are specified in the ``max_pages``.
255 Find pages which have been written and WP them as well::
265 Find pages which have been written, are file backed, not swapped and either
281 the user can find the true soft-dirty pages in case of normal pages. (There may
282 still be extra dirty pages reported for THP or Hugetlb pages.)
296  5. Now the ``PAGEMAP_SCAN`` IOCTL can be used to either just find pages which
