This patch has already been applied to Hirsute as part of the upstream
stable update (bug 1928857). I'm setting the Hirsute nomination as 'Fix
Committed', however the task won't be automatically closed when the
kernel is released.

Title:
[SRU] mpt3sas: only one vSES is handy even IOC has multi vSES

Fix Committed
Status in linux source package in Groovy:

Bug description:
[Impact]
Whenever the driver is adding a vSES to virtual-phys list it is
reinitializing the list head. Hence those vSES devices which were added
previously are lost.
[FIXES]
Stop reinitializing the list every time a new vSES device is added.

CommitID: 4c51f956965120b3441cdd39c358b87daba13e19
[TESTING]
Load the mpt3sas driver on the system where Brodcom's HBA 9500 Tri-Mode
Storage Adapter (IT HBA Aero/Ventura) is connected to two backplanes (so that
two vSES device get configured on the HBA). After loading the driver user
should able to access both the vSES devices. Also even after performing host
reset operation user must able to access both the vSES devices.
i.e. lsscsi must list both the vSES devices after loading the driver and also
after performing host reset operation.
[REGRESSION RISK]
