For I/O to reflinked blocks we always need to write an entire new file system block, and the code enforces the file system block alignment for the entire file if it has any reflinked blocks. Mirror the larger value reported in the statx in the dio_offset_align in the xfs-specific XFS_IOC_DIOINFO ioctl for the same reason. Don't bother adding a new field for the read alignment to this legacy ioctl as all new users should use statx instead.

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.
