Why new code is using the old interface? I thought that the all point for having bsg at all is that new stuff are implemented there in a cleaner interface for example large CDBs. Otherwise what was the point for bsg in the first place? (It was before my time, It would be nice to know?) What is then left unique at bsg after this patch? only bidi?
