Merge tag 'cgroup-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
- Per-cpu cpu usage stats are now tracked
This currently isn't printed out in the cgroupfs interface and can
only be accessed through e.g. BPF. Should decide on a not-too-ugly
way to show per-cpu stats in cgroupfs
- cpuset received some cleanups and prepatory patches for the pending
cpus.exclusive patchset which will allow cpuset partitions to be
created below non-partition parents, which should ease the management
of partition cpusets
- A lot of code and documentation cleanup patches
- tools/testing/selftests/cgroup/test_cpuset.c added
