Well there is a way around it; we just maintain our own reference counter and use that to determine when to complete the original bio. It just seems a shame when there's a ref count in the bio already. But if Jens and Christophe are adamant that bio_chain is going to be the one and only way to access that ref count then I'll allocate another object to hold the ref count. - Joe -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
