|
|
The
|
|
|
|
|
.Fn vm_page_rename
|
|
|
|
|
function removes a page from one object, and adds it to another
|
|
|
|
|
at the given page index.
|
|
|
|
|
The page is added to the given object, and is removed from the
|
|
|
|
|
object that is currently associated with.

|
|
|

If the page is currently on the cache queue it will be deactivated
