Re: [PATCH] genetlink: fix unsigned int comparison with less than zero

quoted

I suppose it could be, since family IDs are allocated in a 16-bit
range
anyway. But family IDs can also never actually be negative, so
having
an unsigned int in the struct makes sense too.

All idr_* API's accept int, rather than unsigned int. This is my
point.

Sure, but that's an internal implementation detail. The struct
genl_family is also an external API towards its users, and there
negative numbers make no sense whatsoever.
