Yeah, this is intended. I wanted to make this API correct. We should use unsigned type for sizes. Unfortunately plugin interface uses int64_t. There are more signed/unsigned miss mach in the plugin interface, but such refactoring is a subject for different patch.  For now i propose that at least we create "correct" public interface for liboffload, so we do not have break api later on.
