From 87d2f8254347879f80b3a834834a6b934dea5ecc Mon Sep 17 00:00:00 2001 From: Alon Levy Date: Sun, 12 May 2013 14:16:28 +0300 Subject: arch_init/ram_load: add error message for block length mismatch Makes it easier to debug situations where the source and target have different ram blocks in a device and migration fails due to that, for instance a BAR size change on a PCI device.
