Series applied, thanks.
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. - Why not more protocol ? If we really think that anonter protocol should be traced, I will modify the code to trace it. I just want to make the code easy and not output useless information.
