There is the chrt tool to change the priority of a task. But the workers  are
created on demand and shared with others so it won't be good.
Whether it is good to use a tasklet or not depends on what you try to
do. But since you can't alter the priority of the tasklet (and only of
tasklet) it is probably not better.
