[xfstests PATCH v3 0/5] overlay: add fsck.overlay basic tests

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

Hi Eryu:

This revision handle your comments in last iteration, please review.

Thanks,
Yi.

Changes since v2:
- Move overlayfs xattrs constants to common/overlay.
- Fix _require_attrs in 201 and 203.
- Fix syntax error in string compare, and modify fsck error handle.
- Modify some code style.

Changes since v1:
- improve _overlay_fsck_dirs helper to accept more than one options.

----------

Background:

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])
