Some people read specs and find things that aren't in the Linux driver (any spec, not a specific one), and think they need to be added. No. We only add them if they make sense, both in terms of use cases, but also as long as they can get implemented cleanly. Parts of basically any spec is garbage and don't necessarily fit within the given subsystem either. The above would make me worried about patches coming from anyone with that mindset. -- Jens Axboe
