The function __scsi_error_from_host_byte, tries to reset the host byte to DID_OK. But that does not happen because of the OR operation. Here is the flow. scsi_softirq_done-> scsi_decide_disposition -> __scsi_error_from_host_byte Let's take an example with DID_NEXUS_FAILURE. In scsi_decide_disposition, result will be set as DID_NEXUS_FAILURE (=0x11). Then in __scsi_error_from_host_byte, when we do OR with DID_OK. Purpose is to reset it back to DID_OK. But that does not happen. This patch fixes this issue. Signed-off-by: Babu Moger Signed-off-by: James Bottomley --- Reading git-diff-tree failed
