From 2cf0148674430b6693c60d42b7eef721bfa9509f Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Wed, 6 Jan 2016 12:23:38 +0000 Subject: [PATCH] Add VMSTATE_STRUCT_VARRAY_KNOWN At the moment we have VMSTATE_STRUCT_ARRAY that requires the field is declared as an array of fixed size. We also have VMSTATE_STRUCT_VARRAY_UINT* that allows a field declared as a pointer, but requires that the length is a field member in the structure being loaded/saved. VMSTATE_STRUCT_VARRAY_KNOWN is for arrays defined as pointers yet we somehow know the length of. Signed-off-by: Dr. David Alan Gilbert Reviewed-by: Michael S. Tsirkin Signed-off-by: Michael S.
