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." Signed-off-by: Michael Halcrow <mhalcrow@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
