[PATCH-cgroup 3/5] cgroup/cpuset: Eliminate unncessary sched domains rebuilds in hotplug

It was found that some hotplug operations may cause multiple rebuild_sched_domains_locked() calls. Some of those intermediate calls may use cpuset states not in the final correct form leading to incorrect sched domain setting. Fix this problem by using the existing force_rebuild flag to inhibit

[PATCH-cgroup 4/5] cgroup/cpuset: Check for partition roots with overlapping CPUs

With the previous commit that eliminates the overlapping partition root corner cases in the hotplug code, the partition roots passed down to generate_sched_domains() should not have overlapping CPUs. Enable overlapping cpuset check for v2 and warn if that happens. This patch also has the benefit

[PATCH-cgroup 2/5] cgroup/cpuset: Clear effective_xcpus on cpus_allowed clearing only if cpus.exclusive not set

Commit e2ffe502ba45 ("cgroup/cpuset: Add cpuset.cpus.exclusive for v2") adds a user writable cpuset.cpus.exclusive file for setting exclusive CPUs to be used for the creation of partitions. Since then effective_xcpus depends on both the cpuset.cpus and cpuset.cpus.exclusive setting. If

[PATCH-cgroup 1/5] cgroup/cpuset: fix panic caused by partcmd_update

[PATCH-cgroup 0/5] cgroup/cpuset: Miscellaneous cpuset updates for 6.12

The first 2 patches in this series fix cpuset bugs found by Chen Ridong. Patch 3 streamlines the sched domain rebuild process for hotplug operation and eliminates the use of intermediate cpuset states for sched domain generation. Patch 4 modifies generate_sched_domains() to check the correctness
