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
