[PATCH 00/11] target_core_mod: ALUA updates

[Hannes Reinecke <hare@suse.de>]

Hi Nic,

here are some updates to TCM ALUA handling. Apart from some
minor fixes and spellchecks the main features are:
- Make supported states configurable:
  We should make the list of supported ALUA states configurable,
  as some setups would possibly like to support a small subset
  of ALUA states only.
- Asynchronous transitioning: I've switched 'transitioning'
  handling to use a workqueue, that should allow us to simulate
  asynchronous transitioning modes. IE TCM should now be capable
  of handling requests while in transitioning, and properly terminate
  these with the correct sense code.
- Include target device descriptor in VPD page 83
  For the ALUA device handler we'd need to identify the target device
  where a given target port belongs to. So include the respective
  values in the VPD page.

Hannes Reinecke (11):
