Sure. I think that FTRACE config is borderline fine, although I think tracing is pretty different from the debug options that don't need the user to actually do anything (like PAGEALLOC_DEBUG). It's the other ones I think were clearly dubious (ok, the MARKERS one isn't "clearly" dubious, since I have no idea why it got enabled, so I guess it would count as "unclearly dubious" then). Linus
