Even when they are trivial/obvious/symmetric. At the time I submitted the topology code there were no users of a blk_limits_io_opt() call so I didn't wire it up. If you need it now, then great. Let's add it to be consistent. -- Martin K. Petersen Oracle Linux Engineering -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
