Hello,

Set of patches that follow this email facilitate movement of hardware
handlers from dm layer to SCSI layer.

Previous set of patches that implemented this was posted on Feb 27:
http://marc.info/?l=linux-scsi&m=120416126328081&w=2

Changes have been made based on feedback received from James and Mike
Anderson.

Following are the changes:
 - Reduced the number of pointers used in scsi_device data structure
   from 2 to 1.
 - Added a special return code for check_sense function to return when
   the sense code is not handled by hardware handler's check_sense fucntion.
 - Added a request pointer argument to hardware handler's prep_fn.
 
Patches are created on top of 2.6.25-rc2-mm1.

Testing has been done with a IBM DS4800 storage device, which means the
infrastructure and the lsi_rdac hardware handler has been tested. Testing
by someone with the EMC hardware and/or HP hardware would be appreciated.

Comments, suggestions solicited.

Thanks,

chandra
