The <fd979c013207> commit intruduced the perf_event_sysfs_show function to display the event_str value of an attr in kernel/event/core.c. But the function returns the value with a newline char. So, if a event also carries a event.unit file, when printing the counter data perf tool formatting goes for a spin. That is, because of the event unit, event name is printed in the newline because of perf_event_sysfs_show returns with a newline char. Now fixing perf core will break API, hencing proposing a fix in the perf tool.
