When enabling Rust in the kernel, we only need to block on the
RANDSTRUCT feature and GCC plugin. The rest of the GCC plugins
are reasonably safe to enable.
[ Originally (years ago) we only had this restriction, but we ended up
restricting also the rest of the GCC plugins 1) to be on the safe side,
2) since compiler plugin support could be going away in the kernel and
3) since mixed builds are best effort so far; so I asked Neal about
his experience enabling the other plugins -- Neal says:
When I originally wrote this patch two years ago to get things
working, Fedora used all the GCC plugins, so I was trying to get GCC +
Rust to work while minimizing the delta on build differences. This was
the combination that worked. We've been carrying this patch in the
Asahi tree for a year now. And while Fedora does not currently have
GCC plugins enabled because it caused issues with some third-party
modules (I think it was the NVIDIA driver, but I'm not sure), it was
around long enough for me to know with some confidence that it was
fine this way.

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.
