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
