do_mod() is a hold-over from when we have different sizes for file offsets and and other internal values for 40 bit XFS filesystems. Hence depending on build flags variables passed to do_mod() could change size. We no longer support those small format filesystems and hence everything is of fixed size theses days, even on 32 bit platforms. As such, we can convert all the do_mod() callers to platform optimised modulus operations as defined by linux/math64.h. Individual conversions depend on the types of variables being used.

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.
