[复现步骤]：
1.下载并编译测试套
git clone --branch kernel-5.10 https://code.alibaba-inc.com/AKTF/xfstests-dev.git
cd xfstests
export CFLAGS="-fcommon"
make configure
./configure
make && make install

2.环境准备
dmsetup remove_all
wipefs -a --force /dev/sdb1
wipefs -a --force /dev/sdb2
mkfs -t ext4 -q -F /dev/sdb1
mkfs -t ext4 -q -F /dev/sdb2
mkdir -p /fs/sdb1
mount -t ext4 /dev/sdb1 /fs/sdb1
mkdir -p /fs/sdb2
mount -t ext4 /dev/sdb2 /fs/sdb2
yum install -y nfs-utils nfs4-acl-tools
mkdir -p /export
mount -t tmpfs nfsv4_root_export /export
mkdir -p /export//fs/sdb1
mount --bind /fs/sdb1 /export//fs/sdb1
echo '/export *(fsid=0,rw,no_subtree_check,no_root_squash)' > /etc/exports
echo '/export//fs/sdb1 *(rw,no_subtree_check,no_root_squash)' >> /etc/exports
mkdir -p /export//fs/sdb2
mount --bind /fs/sdb2 /export//fs/sdb2
echo '/export//fs/sdb2 *(rw,no_subtree_check,no_root_squash)' >> /etc/exports
systemctl restart rpcbind
systemctl restart nfs-server
exportfs -r
mkdir -p /nfs/sdb1
mount -t nfs -o vers=4.2 localhost:/fs/sdb1 /nfs/sdb1
mkdir -p /nfs/sdb2
mount -t nfs -o vers=4.2 localhost:/fs/sdb2 /nfs/sdb2
umount -f -l /nfs/sdb1 /nfs/sdb2 /fs/sdb1 /fs/sdb2
export TEST_DIR=/nfs/sdb1
export TEST_DEV=/dev/sdb1
export nfsvers=4.2
export FSTYP=nfs
export SCRATCH_MNT=/fs/scratch
mkdir /nfs/sdb1 -p
mkdir /fs/scratch -p
chmod 755 -R /fs
export SCRATCH_DEV=/dev/sdb2
export TEST_DIR=/nfs/sdb1
export SCRATCH_MNT=/nfs/sdb2
export TEST_DEV=localhost:/fs/sdb1
export SCRATCH_DEV=localhost:/fs/sdb2
export 'TEST_FS_MOUNT_OPTS=-o vers=4.2'
export 'MOUNT_OPTIONS=-o vers=4.2'
chmod 755 -R /nfs

4.执行测试用例
./check generic/683


[预期结果]：
用例执行成功

[实际结果]：
用例执行失败
