Sorry it took so long. I'm copying Saleem who knows more than I do about this.
That define seems harmless. I checked kernel 3.13 and current trunk
and the defines are the same. For compatibility, I seriously doubt
they're going to change it anytime soon.
I'd just add a comment where that line is from
Saleem, any objections?
