Christoph Hellwig 4490733250 nvme: make SG_IO support optional
Translation SCSI commands to NVMe commands is rather pointless in general
as applications must not expext to be able to use SCSI commands on a
generic block device.

Make the huge translation layer optional and hope no one will ever enable
it in the future.

config BLK_DEV_NVME
tristate "NVM Express block device"
depends on PCI && BLOCK
---help---
The NVM Express driver is for solid state drives directly
connected to the PCI or PCI Express bus. If you know you
don't have one of these, it is safe to answer N.
To compile this driver as a module, choose M here: the
module will be called nvme.
config BLK_DEV_NVME_SCSI
bool "SCSI emulation for NVMe device nodes"
depends on BLK_DEV_NVME
---help---
This adds support for the SG_IO ioctl on the NVMe character
and block devices nodes, as well a a translation for a small
number of selected SCSI commands to NVMe commands to the NVMe
driver. If you don't know what this means you probably want
to say N here, and if you know what it means you probably
want to say N as well.
