Have you attempted to run xfs_repair on the filesystem? There are
alternate super blocks it can attempt to replace the original with.
However, if the swapper managed to get very far into the filesystem
beyond the super block then you probably lost the root inode too,
and at this point recovery becomes very difficult. However, repair may
be able to reconnect inodes into the lost+found dir.
