Unfortunately they can't. E.g. if we remove the detach in dm-mpath but keep the refcounting in scsi_dh we'll leak references. Of if we remove the request_module in dm without adding it to scsi we stop asking for the module. So I'll need to collect ACKs from both sides and find a suitable tree to get this in. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
