Oh, I forgot to mention, that I agree with Alan's comments and have
addressed them in my v2 patches here:
http://marc.info/?l=linux-scsi&m=134312317325650&w=2

The 2 patches Alan has comments are:
http://marc.info/?l=linux-scsi&m=134312311025619&w=2
http://marc.info/?l=linux-scsi&m=134312308225610&w=2

Hi Alan,
Are the v2 patches look OK to you?

And James,
Do you want me to rebase these patches on top of scsi-misc tree?

Thanks,
Aaron
