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. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@fb.com>

|
|
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.

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.
