Makes some sense, although part of the exercise was to get rid of the huge, now unneeded Linux kernel code base. So this approach required a fresh repository, and due to the different paths there is no out-of-the-box patch compatibility between the two. Also I wanted to provide an easy way for people to give it a test. So what I could do is to send the top-most patches against Pekka's github repository, which would eliminate the references to the kernel directory (at the cost of duplicating some files). Once this is settled, acked and applied, one could try to create a new repository with the tools/kvm directory being the new root. Let me know if that makes more sense and I will rework the patches to apply against the current upstream kvmtool. Cheers, Andre. P.S. Although both approaches still provide the kvmtool patch history, they do not compile before the dependency cut patches. If that is an issue, one could think about injecting those new patches back into the repository time line. Admittedly that sounds scary, but would solve the problem. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
