[Qemu-devel] [PATCH] vmstate: Define VARRAY with VMS_ALLOC |
Date: |

This allows dynamic allocation for migrating arrays; copied from
VMSTATE_VARRAY_UINT32 and added VMS_ALLOC.
Signed-off-by: Alexey Kardashevskiy <address@hidden>

This will be used to migrate IOMMU table (sPAPRTCETable) which may or may not
have an actual table allocated; and if allocated, the size is not pre-defined.
