[问题描述]
内部的物理机anolis23 x86环境下，内核为6.6.25-2.2_rc1.an23.x86_64系统上，运行kernel-selftests测试cgroup.test_memcontrol用例fail，有三个失败项

[实际结果]
[root@5f9Lab15 cgroup]# ./test_memcontrol
ok 1 test_memcg_subtree_control
ok 2 test_memcg_current
ok 3 test_memcg_min
not ok 4 test_memcg_low
ok 5 test_memcg_high
ok 6 test_memcg_high_sync
ok 7 test_memcg_max
not ok 8 test_memcg_reclaim
ok 9 test_memcg_oom_events
not ok 10 test_memcg_swap_max
not ok 11 test_memcg_sock
ok 12 test_memcg_oom_group_leaf_events
ok 13 test_memcg_oom_group_parent_events
ok 14 test_memcg_oom_group_score_events


[期望结果]
case pass

[复现步骤]
1. wget https://build.openanolis.cn/kojifiles/output/nightly/anolis-23-20241101.5/compose/os/source/tree/Packages/kernel-6.6.25-2.2_rc1.an23.src.rpm
2. rpm -i kernel-6.6.25-2.2_rc1.an23.src.rpm
   yum-builddep -y /root/rpmbuild/SPECS/kernel.spec 
   rpmbuild -bp /root/rpmbuild/SPECS/kernel.spec 
   cd /root/rpmbuild/BUILD/kernel-*xxx/linux-*
   make -C tools/testing/selftests/
   cd cgroup;make
   ./test_memcontrol
