[PATCH V3 0/3] nvme: fixes for command retry

[Minwoo Im]

Hello,

Here's V3 patch series for Advanced Command Retery Enable (ACRE).  This
series enables command retry feature based on a flag introduced to nvme
controller instance in this series.

This patchset placed ACRE flag check first than REQ_FAILFAST_* cmd_flags
checking.  It makes Set Feature for Host Bevior in reset_work more
meaningful.

Please review.

Thanks!

Since V2:
  - Update commit description more informative. (Sagi)
  - Split [2/2] patch into two patches. (Sagi)
  - Fix condition to return COMPLETE in [2/2]. (Chao and Keith)

Since V1:
  - The first patch has been applied (Christoph).  Removed from this
    series.
  - Update the last patch to take acre flag from the controller
    instance instead of module parameter by updating
    nvme_decide_disposition().  (Chao)

Minwoo Im (3):
  nvme: check all retry delay times in Identify Controller
  nvme: introduce acre flag in nvme_ctrl
  nvme: retry commands based on ACRE flag
