VM_PAGE_BUSY(9) 					   BSD Kernel Developer's Manual					   VM_PAGE_BUSY(9)

NAME
     vm_page_busy, vm_page_flash, vm_page_wakeup -- handle the busying and unbusying of a page

SYNOPSIS
     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/vm_page.h>

     void
     vm_page_busy(vm_page_t m);

     void
     vm_page_flash(vm_page_t m);

     void
     vm_page_wakeup(vm_page_t m);

DESCRIPTION
     These functions handle the busying, unbusying and notification of the unbusying of a page.

     vm_page_busy() sets the VPO_BUSY flag in the page.

     vm_page_flash() checks to see if there is anybody waiting on the page (VPO_WANTED will be set), and if so, clears the VPO_WANTED flag and
     notifies whoever is waiting via wakeup().

     vm_page_wakeup() clears the VPO_BUSY flag on the page, and calls vm_page_flash() in case somebody has been waiting for it.
