The existing REFCOUNT_* LKDTM tests were designed only for testing a narrow portion of CONFIG_REFCOUNT_FULL. This moves the tests to their own file and expands their testing to poke each boundary condition. Since the protections (CONFIG_REFCOUNT_FULL and x86-fast) use different saturation values and reach-zero behavior, those have to be build-time set so the tests can actually validate things are happening at the right places. Notably, the x86-fast protection will fail REFCOUNT_INC_ZERO and REFCOUNT_ADD_ZERO since those conditions are not checked (only overflow is critical to protecting refcount_t). CONFIG_REFCOUNT_FULL will warn for each REFCOUNT_*_NEGATIVE test since it provides zero-pinning behaviors (which allows it to pass REFCOUNT_INC_ZERO and REFCOUNT_ADD_ZERO).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
