From b5b5c569570c414bf0aa80a5ae9480debe07ed58 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Fri, 3 Feb 2017 16:06:48 +0000 Subject: [PATCH] migration: Add VMSTATE_UNUSED_VARRAY_UINT32 VMSTATE_UNUSED_VARRAY_UINT32 is used to skip a chunk of the stream that's an n-element array; note the array size and the dynamic value read never get multiplied so there's no overflow risk.
