The root-only cpuset.cpus.isolated control file shows the current set of isolated CPUs in isolated partitions. This control file is currently exposed only with the cgroup_debug boot command line option which also adds the ".__DEBUG__." prefix. This is actually a useful control file if users want to find out which CPUs are currently in an isolated state by the cpuset controller. Remove CFTYPE_DEBUG flag for this control file and make it available by default without any prefix.
The test_cpuset_prs.sh test script and the cgroup-v2.rst documentation file are also updated accordingly. Minor code change is also made in test_cpuset_prs.sh to avoid false test failure when running on debug kernel.
Applied to cgroup/for-6.8 but I wonder whether this would be useful in non-root cgroups too. e.g. In a delegated partition which is namespaced, wouldn't this be useful too?
Thanks.
