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.

Man page of mmap() says that portable applications should ensure fd argument to be -1 if MAP_ANONYMOUS flag is set as below: ``` The mapping is not backed by any file; its contents are initialized to zero. The fd and offset arguments are ignored; however, some implementations require fd to be -1 if MAP_ANONYMOUS (or MAP_ANON) is specified, and portable applications should ensure this. ``` However, few mmap() calls under selftests/vm/ uses 0 as fd though they use MAP_ANONYMOUS flag. This commit changes the argument to be -1 as recommended. Signed-off-by:SeongJae Park <sj38.park@gmail.com> Acked-by:
