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.
