It will be extended with more features later. Note that he xg_type field will only need a single bit even with realtime group support. For now it fills a hole, but it might be worth to fold it into another field if we can use this space better. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
