Eric Biggers 998646b3c1 fsverity: Switch from crypto_shash to SHA-2 library
fsverity supports two hash algorithms: SHA-256 and SHA-512.  Since both
of these have a library API now, just use the library API instead of
crypto_shash.  Even with multiple algorithms, the library-based code
still ends up being quite a bit simpler, due to how clumsy the
old-school crypto API is.  The library-based code is also more
efficient, since it avoids overheads such as indirect calls.

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 reStructuredText markup notation.

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.
