We can later also add UNMAP support, but it's a lot more complicated to translate due to the different data formats.

Also is there a good reason why they are blacklisted or ist just controller bugs? -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
