The new framework provides an API that is >+ backward compatible with the legacy framework so that existing >+ client drivers continue to work as expected.
Instead of writing "[Tt]he new framework", write "[Tt]his framework". In 4 years, this will no longer be so new. And when the next framework comes along, this will look like it is referencing the new one instead of itself. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
