I suspect it's not new, it's just that you are able to hit the timing just right (and the new include presumable makes that just be much easier). The rules for generating include/generated/autoksyms.h aren't new, they go back to at least 4.7. Adding Nico to the cc, since he's the person to blame for autokeysyms, and might have some idea why the dependency wouldn't be done in time. Linus
