vm_page_hold(9)

The  function  increases the hold count on a page.  This prevents
the page daemon from freeing the page.  should only be  used  for
very temporary wiring of a page, as that page will not be consid‐
ered  for paging or reallocation for as long as its hold count is
greater than zero.  Also note that while wired pages are  removed
from  whatever queue they are on, does not affect the location of
the page.  If it is on a queue prior to the call, it  will  still
be  there afterward.  If the page needs to be held for a long pe‐
riod of time, should be used.  function reduces the hold count on
a page.  If the hold count is zero it is possible that  the  page
will  be  freed by the page daemon.  This manual page was written
