f_fsid really isn't suitable for that. Even filesystems that had UUIDs
since the dawn of days don't always store it there, e.g. XFS. I wish
people had left it with that, but the recent rush to stupidly overload
it with an uuid light and using it in nfs-tools didn't help.
Having an API to expose a UUID to userspace would be useful, but f_fsid
isn't it. If we'll have to add real statvfs syscalls we can add an
f_uuid field, but I'd rather not use up the reamining space in the
statfs structure for that.
