Hello Kefeng.

When these types of lines are changed, please coalesce the
fragmented format pieces into a single string.

It makes grep a bit easier and 80 columns limits don't
apply to formats.

I think using net_ratelimited_function is not particularly
clarifying here.

Maybe net_ratelimited_function should be removed instead
of its use sites expanded.

Perhaps adding macros like #define br_warn_ratelimited()
would be better.

This comment applies to the whole series.
