Good questions. I, perhaps mistakenly, kept the functionality around because there were claims that we'd use it in-tree. That of course never materialized. The fact that people have a lot of trouble even finding the kgdboe sources is quite telling, indeed. Let's kill it, we can pull it back in (perhaps with a better design) if something is proposed in-tree that will need it. But I'm skeptical we ever will need it, and even if such a reinstatement is proposed f.e. for the kgdboe use case it has holes. Consider the case where kgdboe takes a breakpoint in a hardware interrupt handler. What happens? We cannot allow it to perform a full back-and-forth conversation with the remote gdb from such a context. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
