Think about it: how would you react if i added a new file to net/core/ and modified net/Kconfig, and then broke the build? You'd quite likely insist on it being done via net-next-2.6, right? You'd also likely be upset about that kind of change, wouldnt you? Also, has the review feedback from the tracing folks been addressed? Please separate these patches out and lets do this properly, this approach is not acceptable. Ingo
