Patch series "selftests/mm: cow and gup_longterm cleanups", v2. The bulk of these changes modify the cow and gup_longterm tests to report unique and stable names for each test, bringing them into line with the expectations of tooling that works with kselftest. The string reported as a test result is used by tooling to both deduplicate tests and track tests between test runs, using the same string for multiple tests or changing the string depending on test result causes problems for user interfaces and automation such as bisection. It was suggested that converting to use kselftest_harness.h would be a good way of addressing this, however that really wants the set of tests to run to be known at compile time but both test programs dynamically enumarate the set of huge page sizes the system supports and test each. Refactoring to handle this would be even more invasive than these changes which are large but straightforward and repetitive. A version of the main gup_longterm cleanup was previously sent separately, this version factors out the helpers for logging the start of the test since the cow test looks very similar. This patch (of 4): The cow and gup_longterm test programs open code something that looks a lot like the standard ksft_finished() helper to summarise the test results and provide an exit code, convert to use ksft_finished().

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.
