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
