If so, you need to use your modified headers. If not, you can stick with the pristine ones. If you made changes that do not affect the API between kernel-space and user-land, be sure that your changes are not exported. This is usually done using something like: #ifdef __KERNEL__ /* here be dragons */ #endif When the headers are then exported to userland (with make headers_install), the kernel-space stuff gets removed, to leave only the user-land API.
