Revert in mainline is d1aa0c04294e29883d65eac6c2f72fe95cc7c049; patch
had really been pointless and we'd better watch out for its analogues
being introduced.

IMO "fixes a data-race" in patch description has become a serious red flag
for review by now.  Some of them are valid, some are pointless and occasionally
actively harmful.
