Your point is well taken though. Many of these options are "tweaks" that could be dropped form Kconfig and only offered as mount options. > I know that you're > trying to support multiple operating systems with the same codebase, > but once your code is merged it will get patched by other people > making kernel-wide changes, and testing (or even eyeballing) all those > permutations will be far outside the realm of feasibility. To be clear: none of the Kconfig options relate to other OS support. It is my intention to continue to support other OSs and backporting + new features though yaffs.net and patch those into mainstream. While some future changes might make this infeasible, I'll cross that bridge when we get to it. I'm not going to give up yet. -- Charles -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
