Add selftests for cgroup1 hierarchy. The result as follows, $ tools/testing/selftests/bpf/test_progs --name=cgroup1_hierarchy #36/1 cgroup1_hierarchy/test_cgroup1_hierarchy:OK #36/2 cgroup1_hierarchy/test_root_cgid:OK #36/3 cgroup1_hierarchy/test_invalid_level:OK #36/4 cgroup1_hierarchy/test_invalid_cgid:OK #36/5 cgroup1_hierarchy/test_invalid_hid:OK #36/6 cgroup1_hierarchy/test_invalid_cgrp_name:OK #36/7 cgroup1_hierarchy/test_invalid_cgrp_name2:OK #36/8 cgroup1_hierarchy/test_sleepable_prog:OK #36 cgroup1_hierarchy:OK Summary: 1/8 PASSED, 0 SKIPPED, 0 FAILED Besides, I also did some stress test similar to the patch #2 in this series, as follows (with CONFIG_PROVE_RCU_LIST enabled): - Continuously mounting and unmounting named cgroups in some tasks, for example: cgrp_name=$1 while true do mount -t cgroup -o none,name=$cgrp_name none /$cgrp_name umount /$cgrp_name done - Continuously run this selftest concurrently, while true; do ./test_progs --name=cgroup1_hierarchy; done They can ran successfully without any RCU warnings in dmesg.
