vm_page_wire, vm_page_unwire — wire and unwire pages
#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);
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.
