Bug Description
Issue found on Jammy 5.15.0-47.51 (only on Jammy, works with older kernels)
With LTP fork updated (bug 1982995) with Luke's fix for cgroups, tests are no longer failing with:
$cgroup_name already mounted or mount point busy (bug 1949532)
e.g.
mount: /dev/cgroup: ltp_cgroup already mounted or mount point busy.
cgroup_
Instead, the following 10 cpuset related tests:
* cpuset_inherit
* cpuset_base_ops
* cpuset_exclusive
* cpuset_hierarchy
* cpuset_syscall
* cpuset_
* cpuset_load_balance
* cpuset_hotplug
* cpuset_memory
* cpuset_
Are now failing with:
$test_name 1 TFAIL: Could not mount cgroup filesystem with cpuset on /dev/cpuset.
Complete output from one of them:
