vfs: Re-introduce s_uuid in the superblock
Gaah. When commit be85bccaa5aa reverted the export of file system uuid via /proc/<pid>/mountinfo, it also unintentionally removed the s_uuid field in struct super_block. I didn't mean to do that, since filesystems have been taught to fill it in (and we want to keep it for future re-introduction in the mountinfo file). Stupid of me. This adds it back in.
