54 functions wire the page, which prevents it from being reclaimed by the page
55 daemon or when its containing object is destroyed.
56 Both functions require that the page belong to an object.
58 .Fn vm_page_wire_mapped
59 function is for use by the
61 layer following a lookup.
62 This function may fail if mappings of the page are concurrently
63 being destroyed, in which case it will return false.
68 .Fn vm_page_unwire_noq
69 functions release a wiring of a page.
72 function takes a queue index and will insert the page into the
73 corresponding page queue upon releasing its last wiring.
74 If the page does not belong to an object and no other references
78 .Fn vm_page_unwire_noq
79 releases the wiring and returns true if it was the last wiring
