SPC-4 recommends T10 vendor ID based LUN ID was created by concatenating product name and serial number (and istgt follows that). But product name is 16 bytes long by itself, so 16 bytes total length is clearly not enough to fit both. To keep compatibility with existing configurations, pad short device IDs to old length of 16, same as before. This change probably breaks CTL user-level ABI, so control tools should be rebuilt after this change. MFC after: 2 weeks
