While synchronizing what's in trace-cmd vs what's in perf, I came across a change that was made when entering the jbd2 plugin into the tools/lib/traceevent directory. For example, one of the function prototypes went from: unsigned long long process_jbd2_dev_to_name(struct trace_seq *s, unsigned long long *args) to: static unsigned long long process_jbd2_dev_to_name(struct trace_seq *s, unsigned long long *args) I can understand the line break after the long long, but there's no reason to keep args on a separate line.
