From a41796b5537dd90eed0e8a6341dec97f4507f5ed Mon Sep 17 00:00:00 2001 From: Waiman Long Date: Tue, 17 Oct 2023 13:13:41 -0400 Subject: [PATCH] docs/cgroup: Add the list of threaded controllers to cgroup-v2.rst The cgroup-v2 file mentions the concept of threaded controllers which can be used in a threaded cgroup. However, it doesn't mention clearly which controllers are threaded leading to some confusion about what controller can be used requiring some experimentation. Clear this up by explicitly listing the controllers that can be used currently in a threaded cgroup.
