What Greg is telling you is that for you to be able to insmod a module
you need to be running the same kernel version as the source code
against which you have compiled your module.
If you are running kernel 4.0.0, you won't be able to insmod your module
that has been compiled using the "4.0.5-rc7+" source code.
