Cover letter [PATCH 0/7] scsi_dh: Move hardware handlers from dm to SCSI
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
