Frankly, I don't know. Looking at the commit itself, it looks safe,
but it depends what this "extra" data is being used for. From what
I can see, the commit in question just adds the additional opaque
data as a member named "extra", and one is left to guess what it's
use as.

I'd have thought a small structure with named members would have
been the minimum given our standards for in-kernel code.

Why was the "const" dropped in the first place? Does this "extra"
member get written to somewhere?

So, sorry, no idea. This looks to me like a very unsatisfactory
commit, and probably something that got a very poor review.

RMK's Patch system:
FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
