Instead of open-coding the calculations for ESSIV handling, use an ESSIV skcipher which does all of this under the hood. ESSIV was added to the crypto API in v5.4. This is based on a patch from Ard Biesheuvel, but reworked to apply after all the fscrypt changes that went into v5.4. Tested with 'kvm-xfstests -c ext4,f2fs -g encrypt', including the ciphertext verification tests for v1 and v2 encryption policies.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
