[for-next][PATCH 5/8] tracing/probe: Show subsystem name in messages

From: Steven Rostedt
Date: Wed Feb 15 2017 - 09:07:15 EST


From: Masami Hiramatsu <mhiramat@xxxxxxxxxx>

Show "trace_probe:", "trace_kprobe:" and "trace_uprobe:"
headers for each warning/error/info message. This will
help people to notice that kprobe/uprobe events caused
those messages.
