s/nvmef_create_ctrl/nvmf_create_ctrl/ But evem looking at the code later using it I fail how this could work. nvmf_create_ctrl is used to implement writes to the /dev/nvme-fabrics control device to create a fabrics controller out of thin air. The biggest part of it is parsing the options provided as a string, which most importantly includes the actual transport used. But you really need to force a pcie transport type here, which as far as I can tell isn't even added anywhere.
