Can you describe (in the comment) how this customised handling is
performed, please? I.e. describe what exactly happens if the flag is
set, from the point of view of an API consumer.
Also, why do you need this flag at all? The only change I can see is
that you pass additional information to VMStateInfo.get() / .put(),
using NULL if it's not set. Why don't you just always pass the
additional information? If the additional information is not needed by
get() / put() the parameter will be unused anyway.
