Subject: [PATCH 0/2] blk-mq: two patches related with CPU hotplug
Date: Wed, 17 Jan 2018 20:34:42 +0800	[thread overview]
Message-ID: <20180117123444.18393-1-ming.lei@redhat.com> (raw)

Hi Jens,

The 1st one fixes one regression caused by 20e4d81393 ("blk-mq: simplify
queue mapping & schedule with each possisble CPU").

The 2nd one add commens about current race, and convert the WARN_ON
into printk(KERN_WARN) since this warning is harmless.

Thanks,

Ming Lei (2):
  blk-mq: make sure hctx->next_cpu is set correctly
  blk-mq: convert WARN_ON in __blk_mq_run_hw_queue to printk
