Qais Yousef d94a9df490 sched/rt: Remove unnecessary push for unfit tasks ... In task_woken_rt() and switched_to_rto() we try trigger push-pull if the task is unfit. But the logic is found lacking because if the task was the only one running on the CPU, then rt_rq is not in overloaded state and won't trigger a push. The necessity of this logic was under a debate as well, a summary of the discussion can be found in the following thread: https://lore.kernel.org/lkml/20200226160247.iqvdakiqbakk2llz@e107158-lin.cambridge.arm.com/ Remove the logic for now until a better approach is agreed upon.
