I want to change the priority of this thread, so that I can specify the order in which it is scheduled following an interrupt. I'm using: sched_setscheduler(struct task_struct *, int, struct sched_param *); but it doesn't work. I tried to change the priority from the init_module, and also from the Kernel Thread, but there is no way. Kernel version is 2.6.31-11-rt What do I call to change a kernel thread priority? Thanks you very much M?nica -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
