Linus Torvalds ff661eeee2 cgroup: Changes for v6.20
- cpuset changes:
 
   - Continue separating v1 and v2 implementations by moving more
     v1-specific logic into cpuset-v1.c.
 
   - Improve partition handling. Sibling partitions are no longer
     invalidated on cpuset.cpus conflict, cpuset.cpus changes no longer
     fail in v2, and effective_xcpus computation is made consistent.
 
   - Fix partition effective CPUs overlap that caused a warning on cpuset
     removal when sibling partitions shared CPUs.
 
 - Increase the maximum cgroup subsystem count from 16 to 32 to
   accommodate future subsystem additions.
 
 - Misc cleanups and selftest improvements including switching to
   css_is_online() helper, removing dead code and stale documentation
   references, using lockdep_assert_cpuset_lock_held() consistently,
   and adding polling helpers for asynchronously updated cgroup
   statistics.
