The commit message makes for an excellent place to fill in the reader on information that is not obvious from reading the patch. For example...

Given that we are in compat/ space, i.e. in a space meant for platforms lacking POSIX functions and definitions, is it really safe to assume that INET_ADDRSTRLEN is available there?

Are we really, absolutely sure that INET6_ADDRSTRLEN is defined?
Also I wonder: what problem does this patch solve? Is the current way to determine the size of the `tmp` array incorrect?
Please use the commit message space to answer at least these questions.
