[问题发生概率]：
必现

[复现步骤]：
1、git clone https://github.com/kdave/xfstests.git，下载xfstests测试套
2、编译（前提安装了fio）
    cd xfstests/
    make configure
    ./configure
    make -j
    make install
3、设置测试环境，根据磁盘实际名称执行
    mkfs -t ext4 -E lazy_itable_init=0,lazy_journal_init=0 -L OStest -q -F -O bigalloc -C 16k -q -F /dev/nvme1n1p1
    mkfs -t ext4 -E lazy_itable_init=0,lazy_journal_init=0 -L OStest -q -F -O bigalloc -C 16k -q -F /dev/nvme1n1p2
    mkdir /mnt/nvme1n1p1
    mkdir /mnt/nvme1n1p2
    export TEST_DEV=/dev/nvme1n1p1
    export SCRATCH_DEV=/dev/nvme1n1p2
    export FSTYP=ext4
    export SCRATCH_MNT=/mnt/nvme1n1p2
    export TEST_DIR=/mnt/nvme1n1p1
4、执行./check tests/generic/682
