This patch consolidates the CONFIG_PREEMPT and CONFIG_PREEMPT_BKL preemption options into kernel/Kconfig.preempt. This, besides reducing source-code, also enables more centralized tweaking of preemption related options.

|
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.

This option reduces the latency of the kernel by making the

big kernel lock preemptible.
