The first element of a struct bpf_cpumask is a cpumask_t. This is done to allow struct bpf_cpumask to be cast to a struct cpumask. If this element were ever moved to another field, any BPF program passing a struct bpf_cpumask * to a kfunc expecting a const struct cpumask * would immediately fail to load. Add a build-time assertion so this is assumption is captured and verified.

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.
