    Subject[PATCH] (Updated) Preemptible Kernel
    Available at (about 29K):

    for kernel 2.4.10-pre4 and 2.4.9-ac9, respectively.

    Changes since previous post:
    * update for new kernels
    * fix newline/space format buglet

    Changes since original patch:
    * fix compile bug -- CONFIG_HAVE_DEC_LOCK is set as needed, now.

    This patch allows a new config setting, CONFIG_PREEMPT (set in
    `Processor Type and Features') that enables a fully preemptible kernel.
    Preemption is controled via SMP lock points. Control of execution is
    yielded to higher processes even if the currently running process is in
    kernel space.

    This should increase response and decrease latency, and is a highly
    recommended patch for real-time, audio, and embedded systems. However,
    it is recommended for anyone. I use it on my everyday workstation.

    An interesting new article on a preemptible kernel in linux is available
