[Qemu-devel] [PATCH 10/12] ram: save_live_complete() only do one loop


From: Juan Quintela
Subject: [Qemu-devel] [PATCH 10/12] ram: save_live_complete() only do one loop
Date: Thu, 28 Jun 2012 21:22:08 +0200

We were doing the same loop that stage2, and a new one for stage3.  We
only need the one for stage3.
