Hi Fengguang,

I'm slightly confused here: afaik what you're testing is Linus's git HEAD, right? (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
