There was some confusion amongst Meta sched_ext folks regarding whether stashing bpf_rb_root - the tree itself, rather than a single node - was supported. This patch adds a small test which demonstrates this functionality: a local kptr with rb_root is created, a node is created and added to the tree, then the tree is kptr_xchg'd into a mapval.

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.
