Unfortunately, the V4 XFS_IOC_FSGEOMETRY structure is out of space so we can't just add a new field to it. Hence we need to bump the definition to V5 and and treat the V4 ioctl and structure similar to v1 to v3. While doing this, clean up all the definitions associated with the XFS_IOC_FSGEOMETRY ioctl.

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.
