  cgroup/cpuset: Fix race between newly created partition and dying one (2025-04-01 21:46:22 -1000)

----------------------------------------------------------------
cgroup: Fixes for v6.15-rc1

- A number of cpuset remote partition related fixes and cleanups along with
  selftest updates.

- A change from this merge window made cgroup_rstat_updated_list() called
  outside cgroup_rstat_lock leading to list corruptions. Fix it by
  relocating the call inside the lock.

----------------------------------------------------------------

      cgroup: rstat: call cgroup_rstat_updated_list with cgroup_rstat_lock
