[PATCH V2 0/2] sched/deadline: Revised wakeup for suspending constrained dl tasks

[Daniel Bristot de Oliveira]

Hi,

Here is the new version of the patch.

Changes from RFC:
  - dl_runtime and dl_deadline don't get updated that often, so
    save the task's density in a new variable (dl_density) in the
    sched_dl_entity, avoiding a division in the wakeup path.
    (Steven Rostedt & Juri Lelli)

  - Added a patch fixing the comment of the variable dl_bw in the
    sched_dl_entity.

  - Comment fixes (Peter Zijlstra): 
    - Reference the correct dependency (s/edf5835/df8eac8cafce/).
    - Better explanation of the problem and solution.

  - Fixes the laxity check: Use WARN_ON and change the check to one
    that actually works :-) (Peter Zijlstra).

  - Adjust the alignment in the unlikely() in the function (Peter Zijlstra).

Daniel Bristot de Oliveira (2):
  sched/deadline: Comment fix - dl_bw = dl_runtime / dl_period
  sched/deadline: Use the revised wakeup rule for suspending constrained
    dl tasks
