Axel Dörfler 8e0f884c71 * Since the page scanner and thief can work more effectively when no vm_caches ... are locked, there is now a vm_page_reserve_pages() call to ensure upfront that there is a page for me when I need it, and may have locked some caches. * The vm_soft_fault() routine now makes use of that feature. * vm_page_allocate_page() now resets the vm_page::usage_count, so that the file cache does not need to do this in read_chunk_into_cache() and write_chunk_to_cache(). * In cache_io() however, it need to update the usage_count - and it does that now. Since non-mapped caches don't have mappings, the page scanner will punish the cache pages stronger than other pages which is accidently just what we want. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22319 a95241bf-73f2-0310-859d-f6bbb57e9c96		2007-09-26 17:42:25 +00:00
