nvmet: add a generic NVMe target This patch introduces a implementation of NVMe subsystems, controllers and discovery service which allows to export NVMe namespaces across fabrics such as Ethernet, FC etc. The implementation conforms to the NVMe 1.2.1 specification and interoperates with NVMe over fabrics host implementations. Configuration works using configfs, and is best performed using the nvmetcli tool from http://git.infradead.org/users/hch/nvmetcli.git, which also has a detailed explanation of the required steps in the README file.

config NVME_TARGET
tristate "NVMe Target support"
depends on BLOCK
depends on CONFIGFS_FS
help
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.
nvme-loop: add a NVMe loopback host driver This patch implements adds nvme-loop which allows to access local devices exported as NVMe over Fabrics namespaces. This module can be useful for easy evaluation, testing and also feature experimentation. To createa nvme-loop device you need to configure the NVMe target to export a loop port (see the nvmetcli documentaton for that) and then connect to it using nvme connect-all -t loop which requires the very latest nvme-cli version with Fabrics support.

nvme-loop: add configfs dependency CONFIG_NVME_TARGET has a correct CONFIG_CONFIGFS_FS dependency, but the newly added NVME_TARGET_LOOP is missing this, resulting in a link failure: drivers/nvme/built-in.o: In function `nvmet_init_configfs': loop.c:(.init.text+0x2a0): undefined reference to `config_group_init' loop.c:(.init.text+0x2c0): undefined reference to `config_group_init_type_name' loop.c:(.init.text+0x318): undefined reference to `configfs_register_subsystem' drivers/nvme/built-in.o: In function `nvmet_exit_configfs': loop.c:(.exit.text+0x9c): undefined reference to `configfs_unregister_subsystem' This adds the same dependency here.

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