It is stored on disk. nfs_super_get_key() passes it to fscache, which then uses it as the lookup key into the cache for a superblock (the cache is persistent). It became necessary, unfortunately, to distinguish the caching for NFS superblocks based on their connection parameters, as NFS superblocks are distinguished in this manner.
