- bool "Preemptible Kernel"
- help
- This option reduces the latency of the kernel when reacting to
- real-time or interactive events by allowing a low priority process to
- be preempted even if it is in kernel mode executing a system call.
- Unfortunately the kernel code has some race conditions if both
- CONFIG_SMP and CONFIG_PREEMPT are enabled, so this option is
- currently disabled if you are building an SMP kernel.

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