If you add in one patch and remove in another the code motion trackers don't see it. Secondly, you said "This copied code from scsi_lib.c to scatterlist.c and modified it a bit" could you move in one patch and modify in another, so we can see exactly what you're changing. Thirdly, are you sure the pool structure for NVMe should be the same as for SCSI? We don't do buddy pools for 1,2 or 4 entry transactions in SCSI just basically because of heuristics, but the packetised io characteristics of NVMe make single entry lists more likely for it, don't they?
