Merge tag 'cgroup-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo: - Whenever cpuset needs to rebuild sched_domain, it walked all tasks looking for DEADLINE tasks as they need to be accounted on the new domain. Walking all tasks can be expensive and there may not be any DEADLINE tasks at all. Task iteration is now omitted if there are no DEADLINE tasks - Fixes DEADLINE bandwidth misaccounting after task migration failures - When no controller is enabled, -Wstringop-overflow warning is triggered. The fix patch added an early exit which is too eager and got reverted for now. Will fix later - Everything else is minor cleanups * tag 'cgroup-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: Revert "cgroup: Avoid -Wstringop-overflow warnings" cgroup/misc: Expose misc.current on cgroup v2 root cgroup: Avoid -Wstringop-overflow warnings cgroup: remove obsolete comment on cgroup_on_dfl() cgroup: remove unused task_cgroup_path() cgroup/cpuset: remove unneeded header files cgroup: make cgroup_is_threaded() and cgroup_is_thread_root() static rdmacg: fix kernel-doc warnings in rdmacg cgroup: Replace the css_set call with cgroup_get cgroup: remove unused macro for_each_e_css() cgroup: Update out-of-date comment in cgroup_migrate() cgroup: Replace all non-returning strlcpy with strscpy cgroup/cpuset: remove unneeded header files cgroup/cpuset: Free DL BW in case can_attach() fails sched/deadline: Create DL BW alloc, free & check overflow interface cgroup/cpuset: Iterate only if DEADLINE tasks are present sched/cpuset: Keep track of SCHED_DEADLINE task in cpusets sched/cpuset: Bring back cpuset_mutex cgroup/cpuset: Rename functions dealing with DEADLINE accounting
