Compiler warnings can catch bugs at compile time. They can also produce
annoying false positives. Due to this duality, the kernel provides
CONFIG_WERROR so that the developer can choose whether or not they want
compiler warnings to fail the build. Use this same config options to
control whether or not warnings in building kublk fail its build.
