The nvme native multipath provided a separate NVMe status decoder, complicating maintenance as new statuses need to be accounted for. This was already diverging from the generic nvme status decoder, which has implications for other components that rely on accurate generic block errors. This series unifies common code among nvme and device-mapper multipath so that user experience regarding the failover fate of a command is the same. Mike: I split this up because I thought there'd be trouble merging the dm mpath update with the inverted retry logic, but I think you may have rebased the dm-4.16 without that patch, as I'm not seeing it in the most current branch. Keith Busch (5): nvme: Add more command status translation nvme/multipath: Consult blk_status_t for failover block: Provide blk_status_t decoding for retryable errors nvme/multipath: Use blk_retryable dm mpath: Use blk_retryable drivers/md/dm-mpath.c | 19 ++----------------- drivers/nvme/host/core.c | 15 +++++++++++---- drivers/nvme/host/multipath.c | 44 ++----------------------------------------- drivers/nvme/host/nvme.h | 4 ++-- include/linux/blk_types.h | 16 ++++++++++++++++ 5 files changed, 33 insertions(+), 65 deletions(-) -- 2.13.6
