A target reset when I/O is ongoing might result an eventual device offline, as scsi_eh_completed_normally() might return ADD_TO_MLQUEUE in addition to the advertised SUCCESS, FAILED, and NEEDS_RETRY. Which is unfortunate as scsi_send_eh_cmnd() will therefore map ADD_TO_MLQUEUE to FAILED instead of the more appropriate NEEDS_RETRY.
