Currently bindgen has special logic to recognise `size_t` and `ssize_t` and map them to Rust `usize` and `isize`. Similarly, `ptrdiff_t` is mapped to `isize`. However this falls short for `__kernel_size_t`, `__kernel_ssize_t` and `__kernel_ptrdiff_t`. To ensure that they are mapped to usize/isize rather than 32/64 integers depending on platform, blocklist them in bindgen parameters and manually provide their definition.

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.
