From 3459f11a8b16f40f9cde8e4281c2d5dd2ff1a732 Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Thu, 5 Dec 2013 13:04:10 +1030 Subject: virtio_balloon: update_balloon_size(): update correct field According to the virtio spec, the device configuration field that should be updated after an inflation or deflation operation is the 'actual' field, not the 'num_pages' one. Commit 855e0c5288177bcb193f6f6316952d2490478e1c swapped them in update_balloon_size(). Fix it.
