[PATCH 0/5] overlay mount tests

[Amir Goldstein <amir73il@gmail.com>]

Eryu,

overlayfs-next brings some changes of mount behavior described at [1].
Some of the changes depend on the new inodes index opt-in feature and
some don't.

The new test overlay/035 checks for overlay mount behaviors, which are
already present in upstream.

The new test overlay/036 checks for new overlay mount behaviors related
to exclusivity of upper and work dirs among overlay mounts. This test
is expected to fail on upstream kernel, but for a good reason, because
the mount configurations that it tests (sharing upper dir among two
overlay mounts) are not wise at all.

The old test overlay/014 is modified to work well with current upstream
kernel as well as with overlayfs-next with inodes index enabled.

I have one more test for the overlay/mount group to test specific behavior
with index=on, but holding it back until Miklos picks up a patch that fixes
one of the mount verifications that is currently broken on overlayfs-next.

Thanks,
Amir.
