Cgroup subsystem 5_cpuset Subsystem

The cpuset subsystem allocates independent CPU (in multi-core systems) and Memory nodes for tasks in the cgroup. Cpuset_cgroup cpus_allowed and mems_allowed Definitions

CPU and memory nodes contained in the cpuset. The task_struct-> cpus_allowed of the process is consistent with the cpus_allowed of the cpuset to which the process belongs.

In the physical page box (alloc_pages function), you can use cpuset_zone_allowed_softwall to determine whether the current node is in mems_allowed of the cpuset to which the process belongs.
