   // non-null, will be called when initialization is complete. If initialization
   // has already completed, this callback will be invoked within the calling
   // stack. Before the callback is run, calls to |GetAllAvailableStorages| and
   // |GetStorageInfoForPath| may not return the correct results. In addition,
