| 5 | This option reduces the latency of the kernel when reacting to |
| 6 | real-time or interactive events by allowing a low priority process to |
| 7 | be preempted even if it is in kernel mode executing a system call. |
| 8 | This allows applications to run more reliably even when the system is |
| 9 | under load. |

| 11 | Say Y here if you are building a kernel for a desktop, embedded |
| 12 | or real-time system. Say N if you are unsure. |
