4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Biggers <ebiggers@xxxxxxxxxx>
commit 338affb548c243d2af25b1ca628e67819350de6b upstream.
When in effect, add "test_dummy_encryption" to _ext4_show_options() so
that it is shown in /proc/mounts and other relevant procfs files.
