# HEAD: 15257cc2f905dbf5813c0bfdd3c15885f28093c4 sched/fair: Revert force wakeup preemption

Miscellaneous scheduler fixes:

- Fix PELT clock synchronization bug when entering idle

- Disable the NEXT_BUDDY feature, as during extensive testing
Mel found that the negatives outweigh the positives.

- Make wakeup preemption less aggressive, which resulted in
an unreasonable increase in preemption frequency.

Thanks,

Ingo
