Subject: [PATCH 5/5] ext4 crypto: require CONFIG_CRYPTO_CTR if ext4 encryption is enabled
Date: Tue, 12 May 2015 14:59:52 -0400 [thread overview]
Message-ID: <1431457192-3432-5-git-send-email-tytso@mit.edu> (raw)
In-Reply-To: <1431457192-3432-1-git-send-email-tytso@mit.edu>
On arm64 this is apparently needed for CTS mode to function correctly.
Otherwise attempts to use CTS return ENOENT.
