From b8ae0eb320b38415da94a41f75e9f99e0aaff06c Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Fri, 27 Apr 2012 00:45:56 +0530 Subject: virtio: balloon: let host know of updated balloon size before module removal When the balloon module is removed, we deflate the balloon, reclaiming all the pages that were given to the host. However, we don't update the config values for the new balloon size, resulting in the host showing outdated balloon values. The size update is done after each leak and fill operation, only the module removal case was left out. Signed-off-by: Amit Shah Signed-off-by: Michael S.
