This macro is only used by net/ipv6/mcast.c, but there is no reason why it must be BUILD_BUG_ON_NULL(). Replace it with BUILD_BUG_ON_ZERO(), and remove BUILD_BUG_ON_NULL() definition from <linux/build_bug.h>.

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.
