Description of problem: Anolis23 ECS x86_64环境下,kernel-selftests nightly测试，cgroup.test_freezer run fail Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1)下载当前内核对应的kernel源码包 2) rpm -ivh xxx.src.rpm 默认安装到/root下 yum-builddep -y rpmbuild/SPECS/kernel.spec 自动安装前置依赖包，需要yum-utils rpmbuild -bp ./rpmbuild/SPECS/kernel.spec # 这个步骤会打相关的patch， 解压缩tar包，生成BUILD目录 cd rpmbuild/BUILD/kernel-xxx/linux-xxx/ cd /tools/testing/selftests/cgroup make ./test_freezer Actual results: [root@localhost cgroup]# ./test_freezer Cgroup /sys/fs/cgroup/cg_test_simple isn't frozen not ok 1 test_cgfreezer_simple ok 2 test_cgfreezer_tree ok 3 test_cgfreezer_forkbomb ok 4 test_cgfreezer_mkdir ok 5 test_cgfreezer_rmdir ok 6 test_cgfreezer_migrate ok 7 test_cgfreezer_ptrace ok 8 test_cgfreezer_stopped ok 9 test_cgfreezer_ptraced ok 10 test_cgfreezer_vfork Expected results: case pass Additional info: [root@localhost xfstests]# uname -r 5.10.134-61.git.3c4c5575a42e.an23.x86_64 [root@localhost xfstests]# cat /etc/anolis-release Anolis OS release 23 [root@localhost xfstests]# cat /proc/cmdline BOOT_IMAGE=(hd0,msdos1)/boot/vmlinuz-5.10.134-61.git.3c4c5575a42e.an23.x86_64 root=UUID=ece72b7f-465b-433d-8b3b-e5fa53a04642 ro rhgb cryptomgr.notests rcupdate.rcu_cpu_stall_timeout=300 quiet biosdevname=0 net.ifnames=0 console=tty0 console=ttyS0,115200n8 noibrs nvme_core.io_timeout=4294967295 nvme_core.admin_timeout=4294967295 cgroup.memory=nokmem crashkernel=0M-2G:0M,2G-8G:192M,8G-:256M [root@localhost xfstests]# gcc -v Using built-in specs.
