make configure
./configure
make && make install

2.初始化测试盘
dmsetup remove_all
wipefs -a --force /dev/vdb1
wipefs -a --force /dev/vdb2
mkfs -t ext4 -q -F /dev/vdb1
mkfs -t ext4 -q -F /dev/vdb2

mkdir -p /fs/vdb2
mount -t ext4 /dev/vdb2 /fs/vdb2
umount -f -l /fs/vdb1 /fs/vdb2

3.设置环境变量
export TEST_DIR=/fs/vdb1
export TEST_DEV=/dev/vdb1
export FSTYP=ext4
export SCRATCH_DEV=/dev/vdb2
export SCRATCH_MNT=/fs/vdb2

4.执行测试用例
./check -overlay  generic/683


[预期结果]：
用例执行成功

[实际结果]：
用例执行失败

这个现象是否由于aarch64和x86_64的测试配置不同导致，麻烦先排查一下。该测试用例不依赖体系结构，所以aarch64和x86_64的测试结果应该是一样的

---x86是因为没有fsgqa用户导致skip，手动创建此用户，执行报错和aarch64一样

注意到5.10 stable已经修复该问题，准备回合代码
Comment 9 Ferry Meng alibaba_cloud_group 2023-06-26 20:10:18 UTC 
补丁已回合

最新nightly内核，用例已经pass，故closed此缺陷；

---你好，麻烦问下，overlay文件系统下的此用例已经pass，但是ext4-nfsv4.2-2下nfs文件系统的还是失败，是不同问题吗？
