From fb63e5489f7ef5bb4d1a655984ca7ef98ffc5849 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 2 May 2015 10:29:19 -0400 Subject: [PATCH] ext4 crypto: do not select from EXT4_FS_ENCRYPTION This patch adds a tristate EXT4_ENCRYPTION to do the selections for EXT4_FS_ENCRYPTION because selecting from a bool causes all the selected options to be built-in, even if EXT4 itself is a module.
