 494	  Encrypted salt-sector initialization vector (ESSIV) is an IV

 496	  dm-crypt. It uses the hash of the block encryption key as the
 497	  symmetric key for a block encryption pass applied to the input
 498	  IV, making low entropy IV sources more suitable for block
 499	  encryption.
 500
 501	  This driver implements a crypto API template that can be
 502	  instantiated either as a skcipher or as a aead (depending on the
 503	  type of the first template argument), and which defers encryption
 504	  and decryption requests to the encapsulated cipher after applying
 505	  ESSIV to the input IV. Note that in the aead case, it is assumed
 506	  that the keys are presented in the same format used by the authenc
 507	  template, and that the IV appears at the end of the authenticated
 508	  associated data (AAD) region (which is how dm-crypt uses it.)
 509
 510	  Note that the use of ESSIV is not recommended for new deployments,
 511	  and so this only needs to be enabled when interoperability with
 512	  existing encrypted volumes of filesystems is required, or when
 513	  building for a particular system that requires it (e.g., when
