I think the priority of the kernel thread can be changed using "set_user_nice" function. I had found this in following mailing list. http://www.ussg.iu.edu/hypermail/linux/kernel/0510.2/1027.html set_user_nice(current, -19); Older kernels required: task_lock(current); current->nice = -19; task_unlock(current); The kernel thread can set this up when it is first started.

Hi, 1. How to change the priority of the kernel threads created using kernel_thread() API? 2. What is the default priority of the threads created using kernel_thread() API? 3. In latest 2.4 kernel and 2.6 kernel, do we have one-to-one mapping for user space process and POSIX threads to kernel_thread or we have M-to-N mapping?
