Add a statx attribute bit STATX_ATTR_VERITY which will be set if the file has fs-verity enabled. This is the statx() equivalent of FS_VERITY_FL which is returned by FS_IOC_GETFLAGS. This is useful because it allows applications to check whether a file is a verity file without opening it. Opening a verity file can be expensive because the fsverity_info is set up on open, which involves parsing metadata and optionally verifying a cryptographic signature. This is analogous to how various other bits are exposed through both FS_IOC_GETFLAGS and statx(), e.g. the encrypt bit. Reviewed-by: Andreas Dilger <adilger@dilger.ca> Acked-by: Darrick J.

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.
