From 64e3ed0b8ea019597d0b5448fdf05a29eb65ae95 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sat, 30 Apr 2022 22:08:52 -0700 Subject: [PATCH] f2fs: reject test_dummy_encryption when !CONFIG_FS_ENCRYPTION 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.
