From 1df2c9a26fcb2fa32d099f8e9adcdae4207872e3 Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Wed, 16 Oct 2019 10:29:30 +0800 Subject: migration: Define VMSTATE_INSTANCE_ID_ANY Define the new macro VMSTATE_INSTANCE_ID_ANY for callers who wants to auto-generate the vmstate instance ID. Previously it was hard coded as -1 instead of this macro. It helps to change this default value in the follow up patches. No functional change.
