cloud-kernel.git 切换到 4.19.91-27_rc2 tag，qemu 创建 VM，测试没有复现 根据上面贴的 339.out.bad，怀疑是测试环境问题
在执行测试之前，将 SCRATCH_DEV 也就是 /dev/nvme0n1p2 先执行 mkfs.ext4 之后，再执行 ./check -overlay generic/339 就不会报错，应该是 xfstests 更新之后 overlayfs 这块的 setup 逻辑有变化，导致没有给 SCRATCH_DEV 执行 mkfs 操作

已经同步测试同学 @刘伟 适配修改测试步骤
(In reply to Jingbo Xu from comment #4) > 已经同步测试同学 @刘伟 适配修改测试步骤 按照shuming的说法，该问题非回归问题，也无需修改代码，可以在执行时通过环境变量workaround，由测试同学来修改，已经assign回给测试同学。
