Also, it would be better if CONFIG_SPF were defined at the start of the patch series rather than the end, so that as the patches add new code, that code is actually compilable. For bisection purposes. I can understand if this is too much work and effort - we can live with things the way they are now. This patchset is a ton of new code in very sensitive areas and seems to have received little review and test. I can do a merge-and-see-what-happens but it would be quite a risk to send all this upstream based only on my sketchy review and linux-next runtime testing. Can we bribe someone?
