Subject: [PATCH AUTOSEL 5.1 30/59] kselftest/cgroup: fix incorrect test_core skip
Date: Fri, 14 Jun 2019 16:28:14 -0400	[thread overview]
Message-ID: <20190614202843.26941-30-sashal@kernel.org> (raw)
In-Reply-To: <20190614202843.26941-1-sashal@kernel.org>

From: Alex Shi <alex.shi@linux.alibaba.com>

[ 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
...
