commit 6a32c2469c3fbfee8f25bcd20af647326650a6cf upstream. Building any configuration with 'make W=1' produces a warning: kernel/bounds.c:16:6: warning: no previous prototype for 'foo' [-Wmissing-prototypes] When also passing -Werror, this prevents us from building any other files. Nobody ever calls the function, but we can't make it 'static' either since we want the compiler output. Calling it 'main' instead however avoids the warning, because gcc does not insist on having a declaration for main.

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.
