Linux kernel source tree

smatch does not track initialised values as well as gcc, and this triggers many warnings by smatch not presented by gcc. Silence smatch by initialising the error values to -ENODEV, which we use to denote internal errors. (If we see a selftest fail with a silent -ENODEV, we know smatch was right!) v2: smatch was right about igt_create_vma(), it may unlikely fail on the first object allocation which we want to be loud about.

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.
