Or did I just miss it with the holliday break? That series is good to go, and in fact fixes a rash of crash reports which occur on kernels since 3.10, but just started showing up now (triggered by some interaction between consoles over terminal servers and systemd). I didn't bother you about it because it seemed like you were busy. Do you need me to resend this series (and the other 6 series' plus misc fixes)? Regards, Peter Hurley PS - I meant to get to plumbers' last summer but overdue work kept me from going. This would have been easier with a tree to pull from.
