#     Merge tag 'cgroup-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
#     
#     Pull cgroup updates from Tejun Heo:
#     
#      - Yafang Shao added task_get_cgroup1() helper to enable a similar BPF
#        helper so that BPF progs can be more useful on cgroup1 hierarchies.
#        While cgroup1 is mostly in maintenance mode, this addition is very
#        small while having an outsized usefulness for users who are still on
#        cgroup1. Yafang also optimized root cgroup list access by making it
#        RCU protected in the process.
#     
#      - Waiman Long optimized rstat operation leading to substantially lower
#        and more consistent lock hold time while flushing the hierarchical
#        statistics. As the lock can be acquired briefly in various hot paths,
#        this reduction has cascading benefits.
#     
#      - Waiman also improved the quality of isolation for cpuset's isolated
#        partitions. CPUs which are allocated to isolated partitions are now
#        excluded from running unbound work items and cpu_is_isolated() test
#        which is used by vmstat and memcg to reduce interference now includes
#        cpuset isolated CPUs. While it isn't there yet, the hope is
#        eventually reaching parity with the isolation level provided by the
#        `isolcpus` boot param but in a dynamic manner.
#
