How can I know the priority of a kernel thread?

Hello,
How can I know the priority of a kernel thread?

How to check the priority of a kernel thread,
Please, let me know that.

I can know the priority of processes with the following command.
# ps -l
and I can check the kernel threads with the following command.
# ps -aux

But I cannot know the priority of kernel threads with the following command.
# ps -auxl

Try this:

# ps -eo user,pid,priority,command

I think the following command solves this problem...
# ps -l PID
