Commit aa71987472
("nvme: fabrics drivers don't need the nvme-pci
driver") removed the dependency on BLK_DEV_NVME, but the cdoe does
depend on the block layer (which used to be an implicit dependency
through BLK_DEV_NVME).
Otherwise you get various errors from the kbuild test robot random
config testing when that happens to hit a configuration with BLOCK
device support disabled.

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.

This adds support for the SG_IO ioctl on the NVMe character
|
|
and block devices nodes, as well as 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, unless you run a distro that abuses the SCSI
|
|
emulation to provide stable device names for mount by id, like
|
|
some OpenSuSE and SLES versions.

This provides support for the NVMe over Fabrics protocol using
|
|
the RDMA (Infiniband, RoCE, iWarp) transport. This allows you
|
|
to use remote block devices exported using the NVMe protocol set.
|
|
|
|
To configure a NVMe over Fabrics controller use the nvme-cli tool
|
|
from https://github.com/linux-nvme/nvme-cli.
|
|
|
|
If unsure, say N.
