Sungup Moon 5974ea7ce0 nvme: allow duplicate NSIDs for private namespaces ... A NVMe subsystem with multiple controller can have private namespaces that use the same NSID under some conditions: "If Namespace Management, ANA Reporting, or NVM Sets are supported, the NSIDs shall be unique within the NVM subsystem. If the Namespace Management, ANA Reporting, and NVM Sets are not supported, then NSIDs: a) for shared namespace shall be unique; and b) for private namespace are not required to be unique." Reference: Section 6.1.6 NSID and Namespace Usage; NVM Express 1.4c spec. Make sure this specific setup is supported in Linux. Fixes: 9ad1927a3b ("nvme: always search for namespace head") Signed-off-by: Sungup Moon <sungup.moon@samsung.com> [hch: refactored and fixed the controller vs subsystem based naming conflict] Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Sagi Grimberg <sagi@grimberg.me>		2022-03-29 09:29:06 +02:00
