Waiman Long fe8cd2736e cgroup/cpuset: Delay setting of CS_CPU_EXCLUSIVE until valid partition ... The CS_CPU_EXCLUSIVE flag is currently set whenever cpuset.cpus.exclusive is set to make sure that the exclusivity test will be run to ensure its exclusiveness. At the same time, this flag can be changed whenever the partition root state is changed. For example, the CS_CPU_EXCLUSIVE flag will be reset whenever a partition root becomes invalid. This makes using CS_CPU_EXCLUSIVE to ensure exclusiveness a bit fragile. The current scheme also makes setting up a cpuset.cpus.exclusive hierarchy to enable remote partition harder as cpuset.cpus.exclusive cannot overlap with any cpuset.cpus of sibling cpusets if their cpuset.cpus.exclusive aren't set. Solve these issues by deferring the setting of CS_CPU_EXCLUSIVE flag until the cpuset become a valid partition root while adding new checks in validate_change() to ensure that cpuset.cpus.exclusive of sibling cpusets cannot overlap. An additional check is also added to validate_change() to make sure that cpuset.cpus of one cpuset cannot be a subset of cpuset.cpus.exclusive of a sibling cpuset to avoid the problem that none of those CPUs will be available when these exclusive CPUs are extracted out to a newly enabled partition root. The Documentation/admin-guide/cgroup-v2.rst file is updated to document the new constraints.
