Make ext4_mpage_readpages() verify data as it is read from fs-verity files, using the helper functions from fs/verity/. To support both encryption and verity simultaneously, this required refactoring the decryption workflow into a generic "post-read processing" workflow which can do decryption, verification, or both. The case where the ext4 block size is not equal to the PAGE_SIZE is not supported yet, since in that case ext4_mpage_readpages() sometimes falls back to block_read_full_page(), which does not support fs-verity yet.

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.
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.
