Subject: [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 of partition roots with non-overlapping CPUs.
Patch 5 adds new test cases to cover the bugs fixed in patches 1 and 2.

Chen Ridong (1):
  cgroup/cpuset: fix panic caused by partcmd_update

Waiman Long (4):
  cgroup/cpuset: Clear effective_xcpus on cpus_allowed clearing only if
    cpus.exclusive not set
  cgroup/cpuset: Eliminate unncessary sched domains rebuilds in hotplug
  cgroup/cpuset: Check for partition roots with overlapping CPUs
  selftest/cgroup: Add new test cases to test_cpuset_prs.sh
