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.
