If the administrator provided a sunit= mount option, we need to validate the raw parameter, convert the mount option units (512b blocks) into the internal unit (fs blocks), and then validate that the (now cooked) parameter doesn't screw anything up on disk. The incore inode geometry computation can depend on the new sunit option, but a subsequent patch will make validating the cooked value depends on the computed inode geometry, so break the sunit update into two steps.

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.
