I think the only patch I've sent you was direct to you for feedback,
not to the list, and so not intended to be applied. And that was only
cos I thought you might prefer that to looking at the diffs on github.

Would it be ok to create two patch series - one for pull up/down and the
other for set config, if one still needs a lot more work?  
And is it ok to base them on your lineevent_create gotos tidy up
(f6cfbbe2950b2)?
