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.
