How reproducible:
1. 准备环境
#准备disk1 disk2测试盘
disk1=vdb1
disk2=vdb2

dmsetup remove_all
wipefs -a --force /dev/$disk1
wipefs -a --force /dev/$disk2

mkfs -t xfs -L OStest -q -f /dev/$disk1
mkfs -t xfs -L OStest -q -f /dev/$disk2

export TEST_DIR=/fs/$disk1
export TEST_DEV=/dev/$disk1
export FSTYP=xfs
export SCRATCH_MNT=/fs/scratch
mkdir /fs/$disk1 -p
mkdir /fs/scratch -p
export SCRATCH_DEV=/dev/$disk2

2. 下载xfstests测试代码

3. 编译测试源码
cd xfstests-dev
export CFLAGS="-fcommon"
make
make install

4.执行测试用例
./check tests/generic/568



Expected results:
