However, I recommend that we stick to the correct capitalization in the documentation. --- Robert Elliott, HPE Persistent Memory -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
