Many uses of the KUnit resource system are intended to simply defer calling a function until the test exits (be it due to success or failure). The existing kunit_alloc_resource() function is often used for this, but was awkward to use (requiring passing NULL init functions, etc), and returned a resource without incrementing its reference count, which -- while okay for this use-case -- could cause problems in others. Instead, introduce a simple kunit_add_action() API: a simple function (returning nothing, accepting a single void* argument) can be scheduled to be called when the test exits. Deferred actions are called in the opposite order to that which they were registered. This mimics the devres API, devm_add_action(), and also provides kunit_remove_action(), to cancel a deferred action, and kunit_release_action() to trigger one early. This is implemented as a resource under the hood, so the ordering between resource cleanup and deferred functions is maintained.

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.
