As long as you use the new mount api you should pass
FSCONFIG_CMD_CREATE_EXCL which will refuse to mount if a superblock for

Other than that I think a blkdev_get_no_open(dev, false) after
lookup_bdev() should sort the issue out. Christoph?
Or just check for GD_DEAD before the mount proceeds?
This is indeed concise and effective enough. Thank you for your
suggestion.
