Cover letter [PATCH 0/8] scsi_dh update

Hi James,

this is the (hopefully final) update to my scsi_dh patchset. Features are:

- Move device-table matching into the device_handler infrastructure, so that individual drivers don't have to implement it themselves
- Adds a 'dh_state' sysfs attribute for manually attaching device handler to new or unknown disks; this allows to override the internal device tables
- Update the dm-multipath code to attach the device handler specified in the multipath configuration
- Add a cache to speed up lookup of several identical devices
- Update existing EMC, RDAC, and hp_sw device handler to use the new infrastructure
- Add new SPC-3 ALUA device handler

The NetApp device handler has been left out for now as it's still under development.

Please apply.

Cheers,

Hannes
