This brings to light something I have been trying to resolve for a little while now, but I have been finding it difficult to find the necessary time due to competing priorities at work and in my personal time. While the patches in this patchset are a necessary dependency, there are other issues which remain unresolved but which are now public (although the problems were not buried very far in the first place). Further complicating things on my end is that the system with my current work-in-progress patchset was taken offline two days ago and my office is under renovations :/ Give me a day or two to get the patches off that system and I'll post them here and we can start the process of kicking around solutions that work for everyone. -- paul moore www.paul-moore.com
