From f38f8387cbdc4138a492ce9f2a5f04fd3cd3cf33 Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Thu, 29 Mar 2012 12:50:20 +0530 Subject: virtio: drop thaw PM operation The thaw operation was used by the balloon driver, but after the last commit there's no reason to have separate thaw and restore callbacks.
