According to LDD3, the linux/module.h automatically includes the
linux/version, which define some macros to help test the kernel version.
But I search the source tree, and can not find version.h in
include/linux. Where can I find it?

It lives in include/generated/uapi/linux/version.h

If you've never built a kernel in your tree you won't find it though,
because it's created from the Makefile. Look for version_h and
filechk_version.h.
