Add the fsverity_file_open() function, which prepares an fs-verity file to be read from. If not already done, it loads the fs-verity descriptor from the filesystem and sets up an fsverity_info structure for the inode which describes the Merkle tree and contains the file measurement. It also denies all attempts to open verity files for writing. This commit also begins the include/linux/fsverity.h header, which declares the interface between fs/verity/ and filesystems.

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.
