Native nvme 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 user experience regarding the failover fate of a command is the same. v1 -> v2: Fixed blk_status_t used for NVME_SC_LBA_RANGE. Fixed line break formatting. Changed name of new block API for path related errors and added kernel doc for it. Added reviews and acks. Keith Busch (5): nvme: Add more command status translation nvme/multipath: Consult blk_status_t for failover block: Provide blk_status_t decoding for path errors nvme/multipath: Use blk_path_error dm mpath: Use blk_path_error drivers/md/dm-mpath.c | 19 ++----------------- drivers/nvme/host/core.c | 16 ++++++++++++---- drivers/nvme/host/multipath.c | 44 ++----------------------------------------- drivers/nvme/host/nvme.h | 5 +++-- include/linux/blk_types.h | 28 +++++++++++++++++++++++++++ 5 files changed, 47 insertions(+), 65 deletions(-) -- 2.13.6
