Linux Kernel Threads Can Have Priorities and Can Dereference current

My memory failed me on some points of kernel threads today so hopefully this post will solidify my knowledge.

• Kernel threads can have a priority via the "nice" mechanism. It is set using set_user_nice(tsk, nice_level), just as for userspace processes/threads.
• As a consequence of the above point, kernel threads have a task structure and it may be referred to by the current pointer, again, the same as is the case with userspace processes/threads.

set_user_nice() should be called from within the task callback function supplied to kthread_create().
