The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Michael Kelley (1):
      scsi: storvsc: Limit max_sectors for virtual Fibre Channel devices

Steffen Maier (1):
      scsi: zfcp: Defer fc_rport blocking until after ADISC response

Yang Yingliang (1):
      scsi: pm80xx: Fix error return code in pm8001_pci_probe()
