Hi Martin, Given the feedback you've gotten so far I'd imagine you're well on your way with a new patchset (building on your discard merge cleanup, etc). But one thing that seemed odd about the previous set was the order of the patches. I think it'd be more appropriate to put patch 4 and 5 (scsi support) at the beginning of the patchset (block interfaces aren't functional without underlying scsi support). FYI, I'll bounce a message detailing the iSCSI scatter-gather NULL pointer I _always_ hit with dm-io issuing async WRITE_SAME.
