I don't have the configuration to demonstrate the problem - but I have verified that on an alternate configuration, the output of 'cat /sys/class/sas_phy/*/sas_address' is the same before and after the patch, demonstrating a lack of regression.

Multiple SATA disks on the same controller may have the same symlink, making it useless as a unique identifier. [Test Case] On a D05 system w/ SATA disks attached to the onboard SAS controller: $ cat /sys/class/sas_phy/*/sas_address And look for non-unique addresses. [Fix] Addressed upstream by incorporating the scsi host's ID into the generated fake SAS address. [Regression Risk] Limited to the hisi_sas driver's v2 backend. The only Ubuntu system this driver supports is the HiSilicon D05, where we can directly test.
