8692ec023c
introduced a new vm_page_write_modified_page(). * Resolved a TODO: vm_page_write_modified_pages() did not mark a to be written page busy but unlocked its cache which could let someone else steal that page in the mean time. * Moved the logic when to move a page to the active or inactive queue to a new function move_page_to_active_or_inactive_queue(). * Moved page_state_to_string() to vm_page(); it's now also used by the "page" and "page_queue" KDL commands. * Made the output of the "page_queue list" command more useful. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22323 a95241bf-73f2-0310-859d-f6bbb57e9c96
