-From: Jan Beulich <jbeulich@suse.com>
-Subject: memory: don't implicitly unpin for decrease-reservation
-
-It very likely was a mistake (copy-and-paste from domain cleanup code)
-to implicitly unpin here: The caller should really unpin itself before
-(or after, if they so wish) requesting the page to be removed.
-
-This is XSA-252.
