[Dongsheng Yang <yangds.fnst@cn.fujitsu.com>]

Hi Steven,
	The [1/3] in this thread is a copy of 

1390430505-17234-1-git-send-email-yangds.fnst@cn.fujitsu.com.

	At that time, you said you will take this patch if task_nice()
is implemeted as a inline function. Now it is done, I wish you can give
it an ack. If you have a time, please take a look at the other patches
in this thread. Thank you.

Dongsheng Yang (3):
  tracing: Use inline task_nice() to get rid of an open coded
    implementation of it.
  sched/prio: Replace hardcoding of 40 with NICE_WIDTH.
  sched: Use clamp() and clamp_val() to make it more readable.
