NAME

     vm_page_wire, vm_page_unwire — wire and unwire pages

SYNOPSIS

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

     void
     vm_page_wire(vm_page_t m);

     void
     vm_page_unwire(vm_page_t m, int activate);

DESCRIPTION

     The vm_page_wire() function increments the wire count on a page, and
     removes it from whatever queue it is on.

     The vm_page_unwire() function releases one of the wirings on the page.
     When write_count reaches zero the page is placed back onto either the
     active queue (if activate is non-zero) or onto the inactive queue (if
     activate is zero).  If the page is unmanaged (PG_UNMANAGED is set) then
     the page is left on PQ_NONE.
