We need to do this for growfs on the realtime volume too, because a future xfs_repair run could try to fix the filesystem using a backup superblock. This was observed by the online superblock scrubbers while running xfs/233. One can also trigger this by growing an rt volume, cycling the mount, and creating new rt files. Signed-off-by: Darrick J.
