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.
|
|
|
|
|
This allows applications to run more reliably even when the system is
|
|
|
|
|
under load.

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