I am waiting for decision from candidates listed at
http://lkml.kernel.org/r/201510251952.CEF04109.OSOtLFHFVFJMQO@xxxxxxxxxxxxxxxxxxx .
If your series is not for backporting, please choose one from
the candidates. Can you accept the original patch at
http://lkml.kernel.org/r/201510212126.JIF90648.HOOFJVFQLMStOF@xxxxxxxxxxxxxxxxxxx
which implements (1) from the candidates?
