Fair enough; I merged it because I was convinced that we have your Ack for the very same patch in our tree for kGraft, but now that I look again, we apparently don't. So sorry for that. What is your standpoint on this one then, please? > That being said, what is the reason why module relocations are not > supported? That's an addon feature that can be added gradually, it's not crucial for basic functionality. Basically: someone has to write the code, but it's useful even without it. > As far as I can tell right now there is only one simple in-kernel test > case available (which is fine).

For the current feature set of livepatching as-is upstream, no tooling is really hard requirement and the patches are to be written by hand (exactly as the one in the samples/ directory).
