If you have to do a compile-time check for the config symbol, it's better to do it the way you did here than in the caller. My guess was that no caller would actually require this, because when you write a part of a subsystem to interact with the dma-buf infrastructure, you would always disable compilation of an extire file that deals with everything related to struct dma_buf, not just stub out the calls.
