Subject: [PATCH v3 0/4] nvme: improve error handling and ana_state to work well with dm-multipath
Date: Fri, 16 Apr 2021 18:06:33 -0400	[thread overview]
Message-ID: <20210416220637.41111-1-snitzer@redhat.com> (raw)

Hi,

This patchset reflects changes needed to make NVMe error handling and
ANA state updates work well with dm-multipath (which always sets
REQ_FAILFAST_TRANSPORT).

RHEL8 has been carrying an older ~5.9 based version of this patchset
(since RHEL8.3, August 2020).

RHEL9 is coming, would really prefer that these changes land upstream
rather than carry them within RHEL.

All review/feedback welcome.

Thanks,
Mike

v2 -> v3:
- Added Reviewed-by tags to BLK_STS_DO_NOT_RETRY patch.
- Eliminated __nvme_end_req() and added code comment to
  nvme_failup_req() in FAILUP handling patch.

Chao Leng (1):
  nvme: allow local retry for requests with REQ_FAILFAST_TRANSPORT set

Mike Snitzer (3):
  nvme: return BLK_STS_DO_NOT_RETRY if the DNR bit is set
  nvme: introduce FAILUP handling for REQ_FAILFAST_TRANSPORT
  nvme: decouple basic ANA log page re-read support from native
    multipathing
