Hi Baolin, What is the difference between v2 and v3? It's good to include a changelog with each new patch. Regarding the merge, I don't think it makes sense to merge in lsmmc.c if the entire EXT_CSD parser inside it can't be used right now. We might as well just leave it out altogether until it's ready to be used. I don't think there's any point in adding a lot of new unused code just because we might want to use it later. Does that make sense? Thanks, - Chris. -- Chris Ball <http://printf.net/> -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
