Cover letter [PATCH 0/3] Update scsi_dh infrastructure

Hi Chandra,

this patchset updates the scsi_dh infrastructure as laid out in my previous mail. In particular it does

- update the scsi_dh infrastructure to implement a generic device table handling; the static device tables from the individual handlers are copied into a generic list. This allows us to do the checking in the main scsi_dh module instead of having to implement it for every handler. And we can then modify this list dynamically
- Implements a 'dh_state' attribute for the sdev, which allows for manipulating of the device handler itself. So we can now attach, detach, and activate any device handler manually.
- And finally I've updated my SPC-3 alua handler for the new infrastructure. Please include it in your patchset, too.

Patches are relative to your latest patchset.

Cheers,

Hannes
