Hi Jens Axboe There are some problem in 'io_wqe_worker' thread, when the 'io_wqe_worker' be create and Setting the affinity of CPUs in NUMA nodes, due to CPU hotplug, When the last CPU going down, the 'io_wqe_worker' thread will run anywhere. when the CPU in the node goes online again, we should restore their cpu bindings?
Thanks Qiang
