Subject: [PATCH v2 2/7] f2fs: reject test_dummy_encryption when !CONFIG_FS_ENCRYPTION

From: Eric Biggers <[email protected]>

There is no good reason to allow this mount option when the kernel isn't
configured with encryption support. Since this option is only for
testing, we can just fix this; we don't really need to worry about
breaking anyone who might be counting on this option being ignored.
