Description of problem:
anolis23 x86 ECS环境下，nightly kernel-selftest测试，case: cgroup.test_kmem测试异常

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_kmem

Actual results:
[root@qibo-anolis23-nightly-func-x86-1 cgroup]# ./test_kmem
not ok 1 test_kmem_basic
ok 2 test_kmem_memcg_deletion
ok 3 test_kmem_proc_kpagecgroup
not ok 4 test_kmem_kernel_stacks
ok 5 test_kmem_dead_cgroups
memory.current 0
percpu 0
not ok 6 test_percpu_basic
