Merge branch 'for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
"Two cpuset behavior changes:
- cpuset on cgroup2 is changed to enable memory migration based on
nodemask by default.
- A notification is generated when cpuset partition state changes.
All other patches are minor fixes and cleanups"
