scheduling class is inherited from the parent (at fork() time) - thus
kernel threads inherit their creator's scheduling class. Of course they
can change their scheduling class after starting up. In 2.0 most of the
kernel threads were RT - these days most of the kernel system-threads
moved to SCHED_OTHER.
