    sched: Fix sched::sched_stat_wait tracepoint field · e1f84508
    Ingo Molnar authored
    This weird perf trace output:
    
      cc1-9943  [001]  2802.059479616: sched_stat_wait: task: as:9944 wait: 2801938766276 [ns]
    
    Is caused by setting one component field of the delta to zero
    a bit too early. Move it to later.
    
    ( Note, this does not affect the NEW_FAIR_SLEEPERS interactivity bug,
      it's just a reporting bug in essence. )
