There is some talk about how to get child pids when you discuss forking and creating children in the first place... google if this link doesn't have the info you want:

I don't know about the topic you posted, but it seems to me that inside the kernel, you don't HAVE processes - there is only the kernel itself running - processes etc. are in USER space. If you created a process in kernel mode, do you mean to say that it would be a child of the kernel itself - this sounds decidedly dodgy to me.
Can anybody correct me on this?
