From 3dcf63677d4eb7fdfc13290c8558c301d2588fe8 Mon Sep 17 00:00:00 2001 From: David Vrabel Date: Mon, 1 Sep 2014 18:52:44 +0100 Subject: xen/balloon: cancel ballooning if adding new memory failed If the balloon driver is adding additional memory regions to the balloon and add_memory() fails it will likely continuously fail so cancel the balloon operation.
