Thanks for picking this up. However, I hate to throw a wrench in the works, but I had a v10[1] queued up because kbuild found some problems with the series over the weekend. I can send v10 off right away if you want to just replace it in your branch or, if you'd like, I can generate some incremental patches. Let me know which you'd prefer.
