This series introduces changes to scsi and libata error handling for ZBC and ZAC devices. The first patch moves ZBC specific error handling in sd_zbc_complete() to a generic scsi error function that can be used also in libata (second patch). The goal of this change is to limit retries for commands that are identify as not worth retrying (know failure condition) for both scsi/ZBC and libata/ZAC. Without these two patches, only ZBC behaves nicely (commands that are known to fail are retried in the ZAC case). The following 2 snmall patches are simple fixes. The last 2 pacthes are improvements in libata error handling verbosity.
