Merge tag 'cgroup-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo: - 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 * tag 'cgroup-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: (34 commits) cgroup: Do not report unavailable v1 controllers in /proc/cgroups cgroup: Disallow mounting v1 hierarchies without controller implementation cgroup/cpuset: Expose cpuset filesystem with cpuset v1 only cgroup/cpuset: Move cpu.h include to cpuset-internal.h cgroup/cpuset: add sefltest for cpuset v1 cgroup/cpuset: guard cpuset-v1 code under CONFIG_CPUSETS_V1 cgroup/cpuset: rename functions shared between v1 and v2 cgroup/cpuset: move v1 interfaces to cpuset-v1.c cgroup/cpuset: move validate_change_legacy to cpuset-v1.c cgroup/cpuset: move legacy hotplug update to cpuset-v1.c cgroup/cpuset: add callback_lock helper cgroup/cpuset: move memory_spread to cpuset-v1.c cgroup/cpuset: move relax_domain_level to cpuset-v1.c cgroup/cpuset: move memory_pressure to cpuset-v1.c cgroup/cpuset: move common code to cpuset-internal.h cgroup/cpuset: introduce cpuset-v1.c selftest/cgroup: Make test_cpuset_prs.sh deal with pre-isolated CPUs cgroup/cpuset: Account for boot time isolated CPUs cgroup/cpuset: remove use_parent_ecpus of cpuset cgroup/cpuset: remove fetch_xcpus ...
