Hi Ming,

to clarify my comments to your patch to introduce dead_hctx_list here's
a small patchset to address my concerns.
If you agree it would possibly be best to fold it into your patchset.

Patches are relative to the 'nvme-5.2' branch of the nvme git repository
plus the 'V6' iteration of Mings patchset
'blk-mq: fix races related with freeing queue'.

Hannes Reinecke (5):
  blk-mq: rename 'dead_hctx_XX' to 'unused_hctx_XX'
  blk-mq: drop 'hctx_idx' argument from blk_mq_alloc_hctx()
  blk-mq: remove 'nr_queue' argument in blk_mq_exit_hw_queues()
  blk-mq: Set hctx pointer to NULL in blk_mq_exit_hw_queues()
  blk-mq: free q->queue_hw_ctx in blk_mq_exit_queue()
