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
.
