Subject: [PATCH] Affinity of guaranteed pod to non-isolated CPUs
|
|
|
|
This corrects kubelet cpumanager static cpuset tracking for isolcpus
|
|
for versions 1.26.1 and 1.27.5. This ensures that pods specified with
|
|
isolcpus + guaranteed QoS + integer cpu requests, are affined to
|
|
exclusive cpuset and tracked as non-isolated cpus.
