If you know you 11 don't have one of these, it is safe to answer N. 12 13 To compile this driver as a module, choose M here: the 14 module will be called nvme. 15 16config BLK_DEV_NVME_SCSI 17 bool "SCSI emulation for NVMe device nodes" 18 depends on NVME_CORE 19 ---help--- 20 This adds support for the SG_IO ioctl on the NVMe character 21 and block devices nodes, as well as a translation for a small 22 number of selected SCSI commands to NVMe commands to the NVMe 23 driver. If you don't know what this means you probably want 24 to say N here, unless you run a distro that abuses the SCSI 25 emulation to provide stable device names for mount by id, like 26 some OpenSuSE and SLES versions. 27
