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

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