To add to what Kay said: No. Kernel threads cannot really be tracked by userspace in any sensible manner. We won't get SIGCHLD for them, and they cannot be moved outside of the root cgroup. This means we will not get events about their life-time, and cannot track their existance at all. With the current kernel this is hence technically not possible. On top of that though, I am not sure this would even be desirable semantically: babysitting kernel facilities from userspace sounds wrong to me, I think we want a clear hierarchy, that the kernel is responsible for PID 1, and then PID 1 for the rest of the services. But making PID1 also responsible for the kernel appears like the wrong way around.
