Given that we get subtle ptrace breakages quite regularly, it would be nice to see this eventually get resolved. "The implementation is the specification" doesn't seem to work well in this case. BTW, things have improved around UML quite a bit recently, and I think this is to no small amount due to Paolo's work. - Werner -- _________________________________________________________________________ / Werner Almesberger, Buenos Aires, Argentina wa@almesberger.net / /_http://www.almesberger.net/____________________________________________/ - 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/
