- If you configure the kernel to include many drivers built-in instead

- linker will not be able to resolve some long branches and fails to link
- your vmlinux kernel. In that case enabling this option will help you

- Enabling this option will probably slow down your kernel.

- syscalls, it's possible to isolate those applications in

- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.
