I think the motivation for yours is to make small systems without hardware crypto offload slightly faster. That's fine (although I suspect it's more and more obscure), as long as you don't impact the large systems scalability. Can you do some tests with a larger system with very parallel IO (many CPUs submitting) and see if the IO rate is equivalent? If that's given the patches are ok for me. -Andi -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
