From 6a6f6e72eca5ed999689c69d1ac411fe319844a0 Mon Sep 17 00:00:00 2001 From: Wei Liu Date: Wed, 11 Sep 2013 17:54:02 +0000 Subject: xen/balloon: remove BUG_ON in increase_reservation The BUG_ON in increase_reservation is wrong as we have P2M entry ballooned out page set to balloon scratch page, so it might have a valid P2M entry at that point.
