This adds a new nvme_subsystem structure so that we can track multiple controllers that belong to a single subsystem. For now we only use it to store the NQN, and to check that we don't have duplicate NQNs unless the involved subsystems support multiple controllers. Includes code originally from Hannes Reinecke to expose the subsystems in sysfs. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Keith Busch <keith.busch@intel.com> Reviewed-by: Martin K.
