572	  Encrypted salt-sector initialization vector (ESSIV) is an IV
573	  generation method that is used in some cases by fscrypt and/or
574	  dm-crypt. It uses the hash of the block encryption key as the
575	  symmetric key for a block encryption pass applied to the input
576	  IV, making low entropy IV sources more suitable for block
577	  encryption.
578
579	  This driver implements a crypto API template that can be
580	  instantiated either as an skcipher or as an AEAD (depending on the
581	  type of the first template argument), and which defers encryption
582	  and decryption requests to the encapsulated cipher after applying
583	  ESSIV to the input IV. Note that in the AEAD case, it is assumed
584	  that the keys are presented in the same format used by the authenc
585	  template, and that the IV appears at the end of the authenticated
586	  associated data (AAD) region (which is how dm-crypt uses it.)
587
588	  Note that the use of ESSIV is not recommended for new deployments,
589	  and so this only needs to be enabled when interoperability with
590	  existing encrypted volumes of filesystems is required, or when
591	  building for a particular system that requires it (e.g., when
592	  the SoC in question has accelerated CBC but not XTS, making CBC
