Subject: Re: [PATCH mlx5-next] RDMA/mlx5: Don't use cached IRQ affinity mask

Hi,
I've tested this patch and seems problematic at this moment.
maybe this is because of the bug that Steve mentioned in the NVMe 
mailing list. Sagi mentioned that we should fix it in the NVMe/RDMA 
initiator and I'll run his suggestion as well.
BTW, when I run the blk_mq_map_queues it works for every irq affinity.
