From 1d6217a4f9905917ee63315c8ea3d63833792f51 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 8 Jul 2020 14:57:22 -0700 Subject: fscrypt: rename FS_KEY_DERIVATION_NONCE_SIZE The name "FS_KEY_DERIVATION_NONCE_SIZE" is a bit outdated since due to the addition of FSCRYPT_POLICY_FLAG_DIRECT_KEY, the file nonce may now be used as a tweak instead of for key derivation. Also, we're now prefixing the fscrypt constants with "FSCRYPT_" instead of "FS_". Therefore, rename this constant to FSCRYPT_FILE_NONCE_SIZE.
