You can't just pull vm86 out of the kernel anyway. dosemu is a userspace application that depends on it, so pulling this feature out would be a big fat regression, period. I would personally rather not hear about how "it's a legacy program so its userbase is shrinking" used as any sort of excuse to ignore the fact that we shouldn't break userspace. I can even say as a user that vm86 is important to me. By all means, cleaning up vm86 is a good idea. But removing it or fencing it off with a strong deprecation doesn't sound like the right idea. > -- > 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/
