From b6f3067985f12d514187059fb10fe3c877f87cb2 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Tue, 15 Mar 2011 10:23:57 -0400 Subject: xen-balloon: Add interface to retrieve ballooned pages Pages that have been ballooned are useful for other Xen drivers doing grant table actions, because these pages have valid struct page/PFNs but have no valid MFN so are available for remapping.
