First test that we allow overwriting dynptr slots and reinitializing them in unreferenced case, and disallow overwriting for referenced case. Include tests to ensure slices obtained from destroyed dynptrs are being invalidated on their destruction. The destruction needs to be scoped, as in slices of dynptr A should not be invalidated when dynptr B is destroyed. Next, test that MEM_UNINIT doesn't allow writing dynptr stack slots.

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.
