The Linux kernel is a monolithic kernel and, as such, shares the same address space. Although it has the ability to load modules at runtime, the kernel must contain all the symbols the module uses at compilation time. Once the module is loaded, it will share the kernel's address space too.
In this recipe, we will explain how kbuild works.
