This makes it more user-friendly by removing the ordering requirements and adding more descriptive error messages; it also makes it more readable and maintainable. - Add "-f file" support to listing mode (-l). When a -f option is specified, only md(4) devices which have the specified file as backing store are displayed. - Use MD_NAME instead of "md". - Use _PATH_DEV instead of "/dev/". - Return -1 when the specified backing store file is not found in the md device list.
