I ran into the same problem on NVME_TARGET_RDMA now,
which otherwise needs dependencies on both CONFIG_BLOCK and
CONFIGFS_FS:
warning: (NVME_TARGET_LOOP && NVME_TARGET_RDMA) selects NVME_TARGET which has unmet direct dependencies (BLOCK && CONFIGFS_FS)

ns->bdev = blkdev_get_by_path(ns->device_path, FMODE_READ | FMODE_WRITE,
Folding in my patch below should address that too.

This enabled target side support for the NVMe protocol, that is
|
|
it allows the Linux kernel to implement NVMe subsystems and
|
|
controllers and export Linux block devices as NVMe namespaces.
|
|
You need to select at least one of the transports below to make this
|
|
functionality useful.
|
|
|
|
To configure the NVMe target you probably want to use the nvmetcli
|
|
tool from http://git.infradead.org/users/hch/nvmetcli.git.

This enables the NVMe loopback device support, which can be useful
|
|
to test NVMe host and target side features.
