Add a test case to REMOTE_TEST_MATRIX covering the bug fixed by
commit 345f40166694 ("cgroup/cpuset: Return only actually allocated
CPUs during partition invalidation"). The test verifies that when a
sibling partition root changes its cpuset.cpus to overlap with another
partition root, only actually allocated CPUs (effective_xcpus) are
returned to the parent, not all CPUs in cpus_allowed.Signed-off-by: Shaojie Sun <[email protected]> --- tools/testing/selftests/cgroup/test_cpuset_prs.sh | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/tools/testing/selftests/cgroup/test_cpuset_prs.sh b/tools/testing/selftests/cgroup/test_cpuset_prs.sh index 0d41aa0d343d..236cb1b38178 100755 --- a/tools/testing/selftests/cgroup/test_cpuset_prs.sh +++ b/tools/testing/selftests/cgroup/test_cpuset_prs.sh @@ -502,6 +502,12 @@ REMOTE_TEST_MATRIX=( " C1-4:P1 .
