See http://www.infradead.org/rpr.html I've now got 4 copies of this series in less than a week, or rather partial copies as all of them seem to miss a cover letter. Thus I still don't know how the core code in this series is tested or why you've not considered using it for anything but your little corner and thus barely tested. Please slow down a bit and after the nth time please consider testability. Make sure core code regular exercised uses it, or find a way to unit test it at least.
