cgroup: export list of delegatable control files using sysfs Delegatable cgroup v2 control files may require special handling (e.g. chowning), and the exact list of such files varies between kernel versions (and likely to be extended in the future). To guarantee correctness of this list and simplify the life of userspace (systemd, first of all), let's export the list via /sys/kernel/cgroup/delegate pseudo-file. Format is siple: each control file name is printed on a new line. Example: $ cat /sys/kernel/cgroup/delegate cgroup.procs cgroup.subtree_control Signed-off-by: Roman Gushchin <guro@fb.com> Cc: Tejun Heo <tj@kernel.org> Cc: kernel-team@fb.com Signed-off-by: Tejun Heo <tj@kernel.org>
