From 44b1ff319c4781c7ab13f7e119b3114a1e6a52e2 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Mon, 25 Sep 2017 12:29:12 +0100 Subject: migration: pre_save return int Modify the pre_save method on VMStateDescription to return an int rather than void so that it potentially can fail. Changed zillions of devices to make them return 0; the only case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already had an error_report/return case. Note: If you add an error exit in your pre_save you must emit an error_report to say why.
