From: Hui Tang <tanghui20@huawei.com> hulk inclusion category: feature bugzilla: 187173, https://gitee.com/openeuler/kernel/issues/I5G4IH CVE: NA -------------------------------- Dynamic affinity set preferred cpus for task. When the utilization of taskgroup's preferred cpu is low, task only run in cpus preferred to enhance cpu resource locality and reduce interference between task cgroups, otherwise task can burst preferred cpus to use external cpu within cpus allowed.
