> According to the discussion in the mail thread
> https://patchwork.kernel.org/patch/10099243/,
> tcp_set_state tracepoint is renamed to inet_sock_set_state tracepoint and is
> moved to include/trace/events/sock.h.
>
> With this new tracepoint, we can trace AF_INET/AF_INET6 sock state transitions.
> As there's only one single tracepoint for inet, so I didn't create a new trace
> file named trace/events/inet_sock.h, and just place it in
> include/trace/events/sock.h
>
> Currently TCP/DCCP/SCTP state transitions are traced with this tracepoint.

> I just want to make the code easy and not output useless information.
Series applied, thanks.
