And personally I agree.

I am still not sure about renames in include/uapi, perhaps someone can
ack comment this change...

Perhaps we could could even do

- __u16 __pad0;
+ // comment to explain that ->ss is used starting from 4.x,
+ // __pad0 is still here to not break userspace.
+ union { __u16 __pad0; __u16 ss; }

But this is purely cosmetic, and I simply do not know if we should worry
about the potential compilation failure.

I believe both patches are good.
