Linux kernel source tree

Firstly, ensure programs successfully load when using all of the supported maps. Then, extend existing tests to test more cases at runtime. We are currently testing both the synchronous freeing of items and asynchronous destruction when map is freed, but the code needs to be adjusted a bit to be able to also accomodate support for percpu maps. We now do a delete on the item (and update for array maps which has a similar effect for kptrs) to perform a synchronous free of the kptr, and test destruction both for the synchronous and asynchronous deletion. Next time the program runs, it should observe the refcount as 1 since all existing references should have been released by then. By running the program after both possible paths freeing kptrs, we establish that they correctly release resources. Next, we augment the existing test to also test the same code path shared by all local storage maps using a task local storage map.

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.
