alter kthread prio
Timeslice proportion has been increased substantially for -niced tasks. As a result of this kernel threads have much larger timeslices than they previously had.
Change kernel threads' nice value to -5 to bring their timeslice back in line with previous behaviour. This means kernel threads will be less likely to cause large latencies under periods of system stress for normal nice 0 tasks.
