[v2 PATCH -tip 1/6] net: tcp: Add trace events for TCP congestion window tracing

2017-12-18 Thread Masami Hiramatsu
This adds an event to trace TCP stat variables with slightly intrusive trace-event. This uses ftrace/perf event log buffer to trace those state, no needs to prepare own ring-buffer, nor custom user apps. User can use ftrace to trace this event as below; # cd /sys/kernel/debug/tracing # echo
