 cgroup: Changes for v6.12
 
 - cpuset isolation improvements.
 
 - cpuset cgroup1 support is split into its own file behind the new config
   option CONFIG_CPUSET_V1. This makes it the second controller which makes
   cgroup1 support optional after memcg.
 
 - Handling of unavailable v1 controller handling improved during cgroup1
   mount operations.
 
 - union_find applied to cpuset. It makes code simpler and more efficient.
 
 - Reduce spurious events in pids.events.
 
 - Cleanups and other misc changes.
 
 - Contains a merge of cgroup/for-6.11-fixes to receive cpuset fixes that
   further changes build upon.
