Probably. I'll fix it for 3.20. I ran this through 9 hours of testing
and I don't want to change anything unless I need to (if something else
needs to change, I'll make this fix). Even a comment fix needs to go
through my testing before I send to Linus (I was burnt by a comment
fix that wasn't tested a long time ago, you never know what you might
accidentally change).
