[xfstests PATCH v2 0/4] overlay: add fsck.overlay basic tests

["zhangyi (F)" <yi.zhang@huawei.com>]

Hi Eryu:

This is the test cases for the fsck.overlay[1] to test orphan whiteout,
invalid/duplicate reiderct dirs, and the missing impure xattr. These
works only when fsck.overlay exists. (These patchset split form origin
patchset[2])

This revision have already handled all comments form Amir, please review.

Thanks,
Yi.
