517	  Encrypted salt-sector initialization vector (ESSIV) is an IV
518	  generation method that is used in some cases by fscrypt and/or
519	  dm-crypt. It uses the hash of the block encryption key as the
520	  symmetric key for a block encryption pass applied to the input
521	  IV, making low entropy IV sources more suitable for block
522	  encryption.
523
524	  This driver implements a crypto API template that can be
525	  instantiated either as an skcipher or as an AEAD (depending on the
526	  type of the first template argument), and which defers encryption
527	  and decryption requests to the encapsulated cipher after applying
528	  ESSIV to the input IV. Note that in the AEAD case, it is assumed
529	  that the keys are presented in the same format used by the authenc
530	  template, and that the IV appears at the end of the authenticated
531	  associated data (AAD) region (which is how dm-crypt uses it.)
532
533	  Note that the use of ESSIV is not recommended for new deployments,
534	  and so this only needs to be enabled when interoperability with
535	  existing encrypted volumes of filesystems is required, or when
536	  building for a particular system that requires it (e.g., when
537	  the SoC in question has accelerated CBC but not XTS, making CBC
538	  combined with ESSIV the only feasible mode for h/w accelerated
