Subject[PATCH V3] tracing/probe: Show subsystem name in messages
Date
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.

Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org>

Changes in v3:
- Fix a typo.
