No, don't limit us for no good reason, that's not acceptable at all. Patching old kernels when new devices show up that work on those old kernels (like USB network devices that follow the spec with no driver change needed), is not a good idea. So I agree with Oliver here, this isn't acceptable. greg k-h -- 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/
