131 last unmap of subpages.136 subpages is offset up by one. This additional reference is required to137 get race-free detection of unmap of subpages when we have them mapped with141 tracking. The alternative is to alter ->_mapcount in all subpages on each183 comes. Splitting will free up unused subpages.
268 the number of THP subpages. For example, migration of a single 2MB THP that269 has 4KB-size base pages (subpages) will cause this counter to increase by273 PGMIGRATE_SUCCESS, above: this will be increased by the number of subpages,
452 individual subpages.464 page will be split, subpages which belong to VM_LOCKED VMAs will be moved
858 bool "Support setting protections for 4k subpages (subpage_prot syscall)"864 on the 4k subpages of each 64k page.
