    perf hist: Clarify events_stats fields usage · cee75ac7
    Arnaldo Carvalho de Melo authored
    The events_stats.total field is too generic, rename it to .total_period,
    and also add a comment explaining that it is the sum of all the .period
    fields in samples, that is needed because we use auto-freq to avoid
    sampling artifacts.
    
    Ditto for events_stats.lost, that is the sum of all lost_event.lost
    fields, i.e. the number of events the kernel dropped.
    
    Looking at the users, builtin-sched.c can make use of these fields and
    stop doing it again.
