It has been on TODO for a while (with an eye toward NVMe support) but testbeds are hard to come by. All patches welcome. But reports are also welcome, like any crash you hit. Just send me email and I'll fix it up best I can. This work is very timely given NVMe over Fabrics definitely has elevated priority.
