Subject[PATCH 0/6] Add latency_nice priority
This patchset restarts the work about adding a latency nice priority to
describe the latency tolerance of cfs tasks.

The patches [1-4] have been done by Parth:

I have just rebased and moved the set of latency priority outside the
priority update. I have removed the reviewed tag because the patches
are 2 years old.

The patches [5-6] use latency nice priority to decide if a cfs task can
preempt the current running task. Patch 5 gives some tests results with
cyclictests and hackbench to highlight the benefit of latency nice
priority for short interactive task or long intensive tasks.

Parth Shah (4):
sched: Introduce latency-nice as a per-task attribute
sched/core: Propagate parent task's latency requirements to the child
sched: Allow sched_{get,set}attr to change latency_nice of the task
sched/core: Add permission checks for setting the latency_nice value

Vincent Guittot (2):
sched/fair: Take into account latency nice at wakeup
sched/fair: Add sched group latency support
