[xfstests PATCH v2 0/5] overlay: add overlay filesystem dirs check

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

Hi, All:

This patchset implement filesystem check for overlay filesystem, base on
my "overlay: add fsck.overlay basic tests" patchset and works only if
fsck.overlay[1] exists (otherwise not run).

Patch 1 improve and fix _is_mounted helper in common/rc.
Patch 2 hook fsck helper to _check_test_fs & _check_scratch_fs, and
introduce helpers for optionally scratch dirs.
Patch 3~5 modify overlay test cases to do fs check correctly.

Hi, Eryu:

The patch 5/5 conflict with Amir's patchset, let me know if you want me
to rebase it.

Thanks,
Yi.
