Adds a new sample driver `rust_scoped_debugfs` that demonstrates the use of the scoped debugfs APIs. The driver creates a `control` directory with two write-only files, `create` and `remove`. Writing a name and a series of numbers to `create` will create a new subdirectory under a `dynamic` directory. This new subdirectory will contain files that expose the numbers as atomic values. Writing a name to `remove` will remove the corresponding subdirectory from the `dynamic` directory. This sample serves as an example of how to use the `debugfs::Scope` and `debugfs::ScopedDir` APIs to create and manage debugfs entries that are tied to the lifetime of a data structure.

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.
