cgroup: Do not report unavailable v1 controllers in /proc/cgroups (2024-09-10 10:04:28 -1000)
----------------------------------------------------------------
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.
