When only the keyring module is included but auth is not, modpost
complains about the lack of a module license tag:
ERROR: modpost: missing MODULE_LICENSE() in drivers/nvme/common/nvme-common.o
Address this by making both modules buildable standalone,
removing the now unnecessary CONFIG_NVME_COMMON symbol
in the process.
Also, now that NVME_KEYRING config symbol can be either a module or
built-in, the stubs need to check for '#if IS_ENABLED' rather than a
simple '#ifdef'.
Fixes: 9d77eb5277 ("nvme-keyring: register '.nvme' keyring")

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.
