[PATCH 0/3] improve nvme retry mechanism

[Chao Leng]

Nvme protocol define local retry and path error. Nvme retry mechanism
should not care blk status, just need use nvme status. The mechanism is:
non path related error will be retry local, path related error will be
treated by multipath. For nvme mulitpah or other multipath(like
dm-multipath), retry mechanism is same.

Chao Leng (3):
  nvme-core: fix io interrupt caused by non path error
  nvme-core: delete the dependency on blk status
  nvme-core: delete the dependency on REQ_FAILFAST_TRANSPORT
