Maybe we could rename/modify it to be a boot-time testing option for nohz_full? I think we may want to simplify config and kernel command-line options. I don't think it's a good idea to break down every single isolation feature into a kernel command-line option. What we want in the end is having the ability to remove all the noise from a CPU right? Why not have a single option for that?
