From 94ed706d53a9018f24c67374c71f358fca2f0413 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Thu, 2 Oct 2014 19:56:02 +1000 Subject: vmstate: Allow dynamic allocation for VBUFFER during migration This extends use of VMS_ALLOC flag from arrays to VBUFFER as well. This defines VMSTATE_VBUFFER_ALLOC_UINT32 which makes use of VMS_ALLOC and uses uint32_t type for a size.
