Masami Hiramatsu (Google) c88dbbcd88 fprobe, samples: Add use_trace option and show hit/missed counter ... Add use_trace option to use trace_printk() instead of pr_info() so that the handler doesn't involve the RCU operations. And show the hit and missed counter so that the user can check how many times the probe handler hit and missed.
