Maybe this ways is better?

BrowserThread::PostBlockingPoolTask(
    FROM_HERE,
    base::Bind(&FeedbackReport::LoadReportsAndQueue,
               context->GetPath(),

Done.

-          &FeedbackReport::LoadReportsAndQueue, context, base::Bind(
+          &FeedbackReport::LoadReportsAndQueue, context->GetPath(), base::Bind(
               &FeedbackUploader::QueueReport, uploader->AsWeakPtr())));
