That seems pretty unambiguous - 4.5.5 is fine, and 4.5.6 is bad. So
unless it's specific to whatever patches RH is carrying around, we
should be able to just look at the scsi-related stable tree patches in
that region. That seems simple enough.

But theres' really only two (trivial) patches in there:

 - scsi: Add intermediate STARGET_REMOVE state to scsi_target_state
   (f05795d3d771f30a7bdc3a138bf714b06d42aa95 upstream)

 - Revert "scsi: fix soft lockup in scsi_remove_target() on module removal"
   (305c2e71b3d733ec065cb716c76af7d554bd5571 upstream)

as far as I can tell. And neither of them looks very likely, but what
do I know. Adding Martin Petersen and Johannes Thumshirn to the
participants just in case they go "Ahh.."
