[PATCH V2 0/2] blk-mq: two patches related with CPU hotplug

[Ming Lei <ming.lei@xxxxxxxxxx>]

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 comments for current two races, and convert the WARN_ON
into printk(KERN_WARN) with dump_stack() since this warning is harmless.

V2:
	- fix comment and commit log in patch 1
	- use dump_stack() with printk to replace WARN_ON() in patch 2

Thanks,

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