  cgroup/cpuset: Make cpuset_attach_task() skip subpartitions CPUs for top_cpuset (2023-04-12 08:23:58 -1000)

----------------------------------------------------------------
cgroup: Fixes for v6.3-rc6

* Fix several cpuset bugs including one where it wasn't applying the target
  cgroup when tasks are created with CLONE_INTO_CGROUP.

* Fix inversed locking order in cgroup1 freezer implementation.

* Fix garbage cpu.stat::core_sched.forceidle_usec reporting in the root
  cgroup.

This is a relatively big pull request this late in the cycle but the major
contributor is the above mentioned cpuset bug which is rather significant.
