[xfstests PATCH v5 0/7] overlay: add fsck.overlay basic tests

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

Hi All:

Here is the fifth version of test cases for the fsck.overlay[1].

[1] https://github.com/hisilicon/overlayfs-progs

Changes since v4:
- Add _overlay_check_scratch_dirs helper to check optionally dirs
  for tests use _require_overlay_scratch_dirs.
- Modify _overlay_check_fs, make sure overlay is not mounted when
  checking filesystem.

-----------

Changes since v3:
- Modify minor suggestions in 202.
- Add _require_overlay_scratch_dirs helper.
- Replace _require_scratch helper in test cases that finished with
  corrupt filesystem and use optionally test dirs.

Changes since v2:
- Modify some minor suggestions from Amir and Vivek, and simplify code
  in all three test cases.
- Fix duplicate redirect xattr test in 202.
- Add impure xattr test case of general merge directory in 'no impure'
  parent directory.
- Fix fs check failure in other overlay fs test cases. PS: The
  multi-lowers problem in overlay/010 also appears in many other tests,
  _require_scratch() will mis-check the pre-defined underlying dirs
  (not the real test dirs). I think they also need to be modified as this
  patch(06/07) does to check the correct dirs, and I can fix them if you
  think necessary.

Changes since v1:

- Fix _check_scratch_fs hook.
- Remove valid/invalid opaque xattr test.
- Add whiteout test cases of valid/invalid whiteouts in opaque/redirect
  parent directory.
- Add impure xattr test.
