What was the next lines? I bet you it was "PASSED". Which means it did
not fail. This is the second bug you found that has to do with RCU being
called in 'idle'. The one that Paul posted a patch for.

Yeah, PASSED!

I have this patch queued for 3.7. Can I add your 'Tested-by' for it.

Yes, please. Thanks!

Thanks,

I'll test Paul's patch on top of yours right away.
