libata implements a SCSI to ATA Translation Layer and
should comply with the SAT (ANSI INCITS 431-2007) and
SAT-2 (ANSI INCITS 465-2010).

Both standards require that if an ATA device supplies
a World Wide Name (WWN) then it should appear in the
corresponding SCSI device identification VPD page.

Changelog:
   - add NAA descriptor to the device identification VPD
     page for the addressed logical unit. ATA's WWN is
     in NAA(5) format.

The attached patch is against lk 2.6.38 .
