Several of the MM tests have a pattern of printing a description of the test to be run then reporting the actual TAP result using a generic string not connected to the specific test, often in a shared function used by many tests. The name reported typically varies depending on the specific result rather than the test too. This causes problems for tooling that works with test results, the names reported with the results are used to deduplicate tests and track them between runs so both duplicated names and changing names cause trouble for things like UIs and automated bisection. As a first step towards matching these tests better with the expectations of kselftest provide helpers which record the test name as part of the initial print and then use that as part of reporting a result. This is not added as a generic kselftest helper partly because the use of a variable to store the test name doesn't fit well with the header only implementation of kselftest.h and partly because it's not really an intended pattern. Ideally at some point the mm tests that use it will be updated to not need it.

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.
