I agree that the comment of get_random_bytes should be fixed, it's misleading. However I don't think modifying code that has no known bug or weakness because of a rumor and some handwaving is good policy. It's more likely than not to introduce a regression and create real trouble.

If it's ain't broke...

Or in this case:

If you can't prove it's broke...

EDIT: I would also remind everybody that if they really don't trust rdrand for any reason they can just add the "nordrand" boot kernel param and disable this code. It's a non-issue.
