[PATCH 0/4] blk-mq/nvme-tcp: fix timed out related races

[Ming Lei]

Hi,

The 1st 2 patches fixes request completion related races.

The 2nd 3 patches fixes/improves nvme-tcp error recovery.

With the 4 patches, nvme/012 can pass on nvme-tcp in Zhang Yi's test
machine.


Ming Lei (4):
  blk-mq: check rq->state explicitly in
    blk_mq_tagset_count_completed_rqs
  blk-mq: think request as completed if it isn't IN_FLIGHT.
  nvme: tcp: fix race between timeout and normal completion
  nvme: tcp: complete non-IO requests atomically
