Replace every explicit mount/umount of scratch or test devices with helper functions. This allows the next patch to add in hooks to these functions in order to set up & tear down overlayfs on every mount/umount (also adds _test_unmount(), which didn't exist prior) [Eryu Guan rebased the patch agains latest master and replaced more mount/umount with helpers] Signed-off-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eric Sandeen <esandeen@redhat.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>

# Check uid/gid to/from disk with a user namespace. A new file
|
|
# will be created from inside a userns. We check that the uid/gid
|
|
# is correct from both inside the userns and also from init_user_ns.
|
|
# We will then unmount and remount the file system and check the
|
|
# uid/gid from both inside the userns and from init_user_ns to show
|
|
# that the correct uid was flushed and brought back from disk.
