"u_" does not really make any sense, right?

Just use "var" and "modulo" please.

But first, why is this needed at all?  Isn't there an in-kernel function
that should be used instead?

thanks,

You're not asking the right questions.

Is "u_var" a good name?  What does the "u_" even mean?

The \ is not aligned any more.

This macro is rubbish.  How does the wrap around even make sense?
I hope that if you review the code a bit I think you will find that the
wrap around is impossible?  Just fix the two callers and delete this
macro.
