What's the rationale behind this patch set ? I've always been against vb2 controlling the stream state (vb2 should handle buffer management only in my opinion) and I'd like to understand why you want to make it required. I plan to use vb2 in the uvcvideo driver (when vb2 will provide a way to handle device disconnection), and uvcvideo will stop the stream before calling vb2_queue_release() and vb2_streamoff(). Would will I need a stop_stream operation ? -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
