alc 2010-07-09 19:38:30 UTC FreeBSD src repository Modified files: sys/kern vfs_bio.c sys/vm vm_page.c vm_page.h Log: SVN rev 209861 on 2010-07-09 19:38:30Z by alc Add support for the VM_ALLOC_COUNT() hint to vm_page_alloc(). Consequently, the maintenance of vm_pageout_deficit can be localized to just two places: vm_page_alloc() and vm_pageout_scan(). This change also corrects an off-by-one error in the maintenance of vm_pageout_deficit. Historically, the buffer cache functions, allocbuf() and vm_hold_load_pages(), have not taken into account that vm_page_alloc() already increments vm_pageout_deficit by one.
