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
