      Adding DIF Type 2 protection support, as well as turning on 32 byte cdb's,
      and setting the cdb length for > 16 byte in the SCSI_IO->control parameter.

      [SCSI] ibmvscsi: Fix oops when an interrupt is pending during probe · 8f83d768
      Anton Blanchard authored
      
      
      A driver needs to be ready to take an interrupt as soon as it registers
      an interrupt handler. I noticed the following oops when testing kdump:

      srp_task needs to be setup before request_irq. The patch below fixes the oops.
