Subject[PATCH v2 0/7] Add latency_nice priority
Date
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:
https://lore.kernel.org/lkml/20200228090755.22829-1-parth@linux.ibm.com/

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 [5-7] 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.


Change since v1:
- fix typo
- move some codes in the right patch to make bisect happy
- simplify and fixed how the weight is computed
- added support of sched core patch 7

Parth Shah (4):
sched: Introduce latency-nice as a per-task attribute
sched/core: Propagate parent task's latency requirements to the child
task
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 (3):
sched/fair: Take into account latency nice at wakeup
sched/fair: Add sched group latency support
sched/core: support latency nice with sched core
