Currently, KBUILD_MODNAME is defined only when $(modname) contains just one word. If an object is shared among multiple modules, undefined KBUILD_MODNAME could cause a build error. For example, if CONFIG_DYNAMIC_DEBUG is enabled, any call of printk() populates .modname, then fails to build due to undefined KBUILD_MODNAME. Take the following code as an example: obj-m += foo.o obj-m += bar.o foo-objs := foo-bar-common.o foo-only.o bar-objs := foo-bar-common.o bar-only.o In this case, there is room for argument what to define for KBUILD_MODNAME when foo-bar-common.o is being compiled. "foo", "bar", or what else? One idea is to define colon-separated modules that share the object, in this case, "bar:foo" (modules are sorted alphabetically by $(sort ...)).

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.
