Thanks. It might be worth to only set in in the host in fact. Also please just remove the code about lock contention in scsi_mq_prep_fn - the XXX really doesn't apply anymore and I think the code should be self-explaining enough to not need a comment. Otherwise the patch looks good to me. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
