Yewwww.... .. I suppose. If we were needlessly pedantic, then perhaps the libata-bmdma.c should be renamed to libata-sff.c, and the libata-sff.c should be renamed libata-tf.c But there's probably been a document or two since then, where the SFF folks have documented the TF interfaces, too. So.. whatever. :)
