From d33793fb89c2e3576d1f219e58f59365484f475e Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 10 Apr 2015 16:28:26 -0700 Subject: f2fs crypto: add f2fs encryption Kconfig This patch adds f2fs encryption config. This patch integrates: "ext4 crypto: require CONFIG_CRYPTO_CTR if ext4 encryption is enabled On arm64 this is apparently needed for CTS mode to function correctly. Otherwise attempts to use CTS return ENOENT."
