Update trace-cmd show and stat to display more tracefs information:

 trace-cmd show --buffer-subbuf-size
 trace-cmd show --buffer_percent

And use tracefs_instance_file_read() instead of open coding it in
trace-cmd stat.

Steven Rostedt (Google) (4):
  trace-cmd show: Re-arrange the enum long option values
  trace-cmd show: Add --buffer-subbuf-size option
  trace-cmd show: Add option to read buffer_percent
  trace-cmd stat: Use tracefs_instance_file_read()
