It might work somewhere, but there are a lot of (X * 65536 + Y * 256 + Z) assumptions all around the world. So this doesn't look like a good idea.
Ok, so what happens if we "wrap"? What will break with that? At first glance, I can't see anything as we keep the padding the same, and our build scripts seem to pick the number up from the Makefile and treat it like a string.
It's only the crazy out-of-tree kernel stuff that wants to do minor version checks that might go boom. And frankly, I'm not all that concerned if they have problems :)
Agreed. But currently, sublevel won't "wrap", it will "overflow" to patchlevel. And that might be a problem. So we might need to update the header generation using e.g. "sublevel & 0xff" (wrap around) or "sublevel > 255 : 255 : sublevel" (be monotonic and get stuck at 255).
In both LINUX_VERSION_CODE generation and KERNEL_VERSION proper.
thanks,
