(I got that from 3.7.0-01930-gbff6343). Tejun stated that he queued that commit for 3.9, and indeed I don't see it in Linus's master as of today. Therefore, I'm not quite sure how you're hitting it in your bisection - the only place that commit is supposed to be at is in Tejun's -next/linux-next trees. Thanks, Sasha
