However, it reduces preemption events of running threads.And while the rebalance thread is ually not compute bound, it does cause a considerable amount of I/O. By increasing its nice level from 0 to 19 we also implicitly reduce the thread's best-effort I/O scheduling class level from 4 to 7. Therefore, the rebalance thread's I/O operations will be deprioritized over standard I/O operations.Is there a patch 1/2?
Sorry, patch 1/2 was unfortunately not send to linux-bcachefs@. You can find it at
