Subject: [PATCH] md: improve message about invalid superblock during
autodetect
People try to use raid auto-detect with version-1 superblocks (which is not
supported) and get confused when they are told they have an invalid
superblock.
So be more explicit, and say it it is not a valid v0.90 superblock.
