That said, I doubt it's a very common problem in practice. I'm pretty sure nobody really cares, and almost nobody really wants to run really old binaries. So it's almost certainly not worth it (and the one time I had it happen, I didn't bother to do it right, I just hacked around it and obviously never committed the hack). I just find it a bit sad how well we actually _can_ run old binaries, but sometimes there are these new things that were literally designed to break them. Of course, the much more common breakage comes from not having access to old shared libraries etc totally user-space issues. The few kernel cases of EOVERFLOW are totally hidden by just distro differences over time. If the binary I had hadn't been statically linked, I wouldn't have had a chance, I suspect. (Of course, static linking wasn't exactly unusual for really old binaries) Linus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
