    ovl: encode non-indexed upper file handles · b305e844

    We only need to encode origin if there is a chance that the same object was
    encoded pre copy up and then we need to stay consistent with the same
    encoding also after copy up.
    
    In case a non-pure upper is not indexed, then it was copied up before NFS
    export support was enabled. In that case, we don't need to worry about
    staying consistent with pre copy up encoding and we encode an upper file
    handle.
    
    This mitigates the problem that with no index, we cannot find an upper
    inode from origin inode, so we cannot decode a non-indexed upper from
    origin file handle.
