It seems so because the implementation nowwhere refers to the inode parameter. But I guess it won't be OK to just remove this parameter from the declaraion and the implemetation because some other NVidia code may refer to this parameter, pass it and so on. Potentially scrambling (spoiling) the parameter stack.

Ok, as I said - it is nowhere used. So this is not a problem.
