Subject[GIT PULL] First round of SCSI updates for the 3.3+ merge window
From
Date
The patch contains the usual assortment of driver updates (lpfc,
qla2xxx, qla4xxx, bfa, bnx2fc, bnx2i, isci, fcoe, hpsa) plus a huge
amount of infrastructure work in the SAS library and transport class as
well as an iSCSI update. There's also a new SCSI based virtio driver.

The patch is available here:
