  4. Compile the module using this kernel tree.

How do I compile only one kernel module?

create new folder somewhere for the module source (example: extra) and copy only source files (from the kernel source or somewhere else) related to the module needed to be build into this new folder. copy /boot/config-`uname -r` file (example: /boot/config-4.8. 0-46-generic) into kernel source folder file .
