NAME¶vm_page_busy, vm_page_flash, vm_page_wakeup — handle the busying and unbusying of a page
#include <vm/vm_page.h> void
vm_page_busy(vm_page_t m); void
vm_page_flash(vm_page_t m); void
DESCRIPTION¶These functions handle the busying, unbusying and notification of the unbusying of a page. vm_page_busy() sets the
VPO_BUSYflag in the page. vm_page_flash() checks to see if there is anybody waiting on the page (
VPO_WANTEDwill be set), and if so, clears the
VPO_WANTEDflag and notifies whoever is waiting via wakeup(). vm_page_wakeup() clears the
VPO_BUSYflag on the page, and calls vm_page_flash() in case somebody has been waiting for it.
