[复现步骤]：
1.下载测试代码
2.编译
cd xfstests-dev
export CFLAGS="-fcommon"
make
make install

3.初始化环境，执行用例
wipefs -a --force /dev/vdb1  
wipefs -a --force /dev/vdb2
mkfs -t xfs -L OStest -q -f /dev/vdb1
mkfs -t xfs -L OStest -q -f /dev/vdb2

export FSTYP=xfs
export TEST_DIR=/fs/vdb1
export TEST_DEV=/dev/vdb1
export SCRATCH_MNT=/fs/vdb2
export SCRATCH_DEV=/dev/vdb2
umount -l /fs/vdb1 /fs/vdb2
mkdir -p /fs/vdb1 /fs/vdb2

./check xfs/546

[预期结果]：
用例执行成功

[实际结果]：
用例执行失败
