The normal mechanisms for allocating isolated CPUs do not allow
a mix of isolated and exclusive CPUs in the same container. In
order to allow this in *very* limited cases where the pod spec
is known in advance we will add the ability to disable the normal
isolcpus behaviour.
If the file "/etc/kubernetes/ignore_isolcpus" exists, then kubelet
will basically forget everything it knows about isolcpus and just
treat them like regular CPUs.
The admin user can then rely on the fact that CPU allocation is
deterministic to ensure that the isolcpus they configure end up being
allocated to the correct pods.
