The kernel would like to have all stack VLA usage removed[1]. This is a test function so the execution speed is not critical. We can allocate memory for this buffer instead of using a VLA. If kmalloc() fails just return. Allocate buffer with kmalloc(). [1]: https://lkml.org/lkml/2018/3/7/621 Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Rob Herring <robh@kernel.org>
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.
