As good community neighbors, we see a generic issue in the Kconfig language, a tool used frequently outside of just the Linux kernel, and would like to contribute back. Ideally without having first gone off, designed and implemented something, and then been told it's all wrong and to rewrite it first. So what level of interest is there in this? As I pointed out in that thread, I believe barebox has examples where some keyword like we're proposing here would help them (and yes, there's only a dozen or so symbols so it's also manageable without anything special), and Simon believes Zephyr will be in a similar situation soon enough (which doesn't use the kernel's implementation of the language). Frankly, I keep going back to "tristate" is just the original example of what we're talking about here (CONFIG_FOO=n, CONFIG_FOO_MODULE=y), not that I'm suggesting we would remove the tristate word. So we would really like to make sure as many people and projects are aware, as possible. And as Simon asked in the thread, what about code refactoring that makes further maintenance easier? Clearly, such patches would need to be against the current appropriate tree. -- Tom
