I don't seem to be the one that can declare such things, which is why I pulled _AUTO out of -mm before the 4.15 merge window. It was breaking akpm and Arnd, which seemed like a serious problem, especially since you've yelled about how it's very bad to break builds, etc. > What I would worry about primarily is not one of the odd developers > who can upgrade, but random people in the wild.

You have no objection from me at all on this. I have been yelled at repeatedly (unjustly in this thread even) for "forcing options" on people. I worked very hard to NOT break people with this, so it didn't seem like a good plan to knowingly break builds. (And the other options, _REGULAR and _STRONG, _do_ actually break the build if you have a broken compiler. But for _AUTO, that seemed like a very bad idea. I could only imagine the flames.) -Kees -- Kees Cook Pixel Security -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
