./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/vdb1
mount -t ext4 /dev/vdb1 /fs/vdb1
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  overlay/075


[预期结果]：
用例执行成功

[实际结果]：
用例执行失败

请安排一位同学分析一下，这是新版xftests出现的问题。
Comment 7 gaoxiang alibaba_cloud_group 2023-06-13 16:56:00 UTC 
https://lore.kernel.org/linux-fsdevel/20210325193755.294925-1-mszeredi@redhat.com/

VFS和各个文件系统需要backport一个series：
https://lore.kernel.org/linux-fsdevel/20210325193755.294925-1-mszeredi@redhat.com/

这个测试用来测试overlayfs在copyup时append-only等等flag是否继承了，目前认为这些flag copyup时没有继承影响较小(stable也没有backport这个系列），当然有时间也可以backport下整个系列。
Comment 8 gaoxiang alibaba_cloud_group 2023-10-08 11:50:00 UTC 
暂不修复。
