Not at the moment. Could expand more on why you feel the need for this? Is this something you want just for experimentation or would you want to use it in production? How do you know which blocks you want to pin? If the pinned blocks are in large regions do you actually just want to build a device that is composed of linear mappings to a mixture of spindle and ssd devices? - Joe -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
