3 | bool "Preemptible Kernel" | |
4 | help | |
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. | |
