All disks have XFS on top of bcache running. The udev rules were changed to reject bcache devices with a pre-existing superblock (xfs in your case). This was done to fail early when there's a risk of exposing an unsynchronised backend device, which would be a bad thing™. You can remove the stray superblocks with wipefs. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
