I think he's trying to go the other way, make his thread the highest priority to blow anything else in the system out of the water.

If called with the current task's state set to TASK_(UN)INTERRUPTIBLE, it puts the task to sleep. Kernel threads are preemptible if the kernel is configured with CONFIG_PREEMPT. What exactly are you trying to do? If you're new to Linux kernel programming, I suggest you read Robert Love's book "Linux Kernel Development". "Linux Device Drivers" by J.Corbet, A.Rubini and G.Kroah-Hartman will be very helpful too and it is available online: http://lwn.net/Kernel/LDD3/ Michal - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
