Nit: This function name doesn't make sense to me anymore.

Previous name emphasized it was on blocking pool, i.e. where it should be run.
New name just says "Blocking" which I don't think makes sense. Also, comment is
still as before.

Please name it in a way that makes more sense.

 
   // Receives |google_update_metrics| from a blocking pool thread and runs
   // |done_callback|.
   void ReceiveGoogleUpdateData(
       const base::Closure& done_callback,
       const GoogleUpdateMetrics& google_update_metrics);
 
   // Google Update metrics that were fetched via GetGoogleUpdateData(). Will be
   // filled in only after the successful completion of GetGoogleUpdateData().
   GoogleUpdateMetrics google_update_metrics_;
 
   base::WeakPtrFactory<GoogleUpdateMetricsProviderWin> weak_ptr_factory_;
 
   DISALLOW_COPY_AND_ASSIGN(GoogleUpdateMetricsProviderWin);
 };
