Enabling the config only adds the workaround which causes the kernel to be a bit bigger (adds -maccumulate-outgoing-args) and does not break the kernel. When we have the test, we wont need to add this workaround if the test passes. This is still a new feature, and until we are sure its safe, we should have it as an option. There's lots of things in the kernel that will break with all{yes,mod}config. I know, because I keep hitting them with my randconfig tests. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
