[ Upstream commit f97f3f8839eb9de5843066d80819884f7722c8c5 ]
The test_core will skip the
test_cgcore_no_internal_process_constraint_on_threads test case if the
'cpu' controller missing in root's subtree_control. In fact we need to
set the 'cpu' in subtree_control, to make the testing meaningful.
./test_core
...
ok 4 # skip test_cgcore_no_internal_process_constraint_on_threads
