Considering the facts that:
1. I proposed the said flag and Al didn't think it was needed [1]
2. ext4 already sets s_uuid without any flag for a long time now
3. A similar patch was queued for v4.12 to set s_uuid for xfs without any flag

I think it would be right to take Oleksij's patch as is.

FYI, my current work on 'constant inode numbers for overlayfs' requires that
underlying filesystem had set a non-zero s_uuid. Not sure if that matters for
ubifs+overlayfs users.
