As of now, there're two sk_family are traced with sock:inet_sock_set_state, which are AF_INET and AF_INET6. So the sk_family are exposed as well. Then we can conveniently use it to do the filter. Both sk_family and sk_protocol are showed in the printk message, so we need not expose them as tracepoint arguments.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
