Does it make sense to keep it as a helper then? I did take a brief look at the code, and I really don't understand why the heck it even deals with bios to start with. Like all the other nvme transports it is a blk-mq driver and should iterate over segments in a request and more or less ignore bios. Something is horribly wrong in the design. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
