Date: Sat, 30 Apr 2022 22:08:52 -0700 From: Eric Biggers <ebiggers@...nel.org> To: linux-fscrypt@...r.kernel.org, linux-ext4@...r.kernel.org, linux-f2fs-devel@...ts.sourceforge.net Cc: Lukas Czerner <lczerner@...hat.com>, Theodore Ts'o <tytso@....edu>, Jaegeuk Kim <jaegeuk@...nel.org>, Jeff Layton <jlayton@...nel.org> Subject: [PATCH v2 2/7] f2fs: reject test_dummy_encryption when !CONFIG_FS_ENCRYPTION From: Eric Biggers <ebiggers@...gle.com> 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.
