But why do we need a CONFIG flag for something that has no content?
That is, I do not see anything much; except the 'I want to stay in userspace and kill me otherwise' flag, and I'm not sure that warrants a CONFIG flag like this.
Other than that, its all a combination of NOHZ_FULL and cpusets/isolcpus and whatnot.
