How can I review this?  What you're proposing certainly isn't a
backport.  What you're actually trying to do is to port around this
commit:

ommit bc85dc500f9df9b2eec15077e5046672c46adeaa
Author: Christoph Hellwig <hch@lst.de>
Date:   Thu May 1 16:51:03 2014 +0200

    scsi: remove scsi_end_request

Have you tried simply backporting that to your tree and then applying
to work around?
