PATCH RESEND 3/3 multipath: implement controller framework for hardware handlers
Hi Alasdair,
This is a rework of the patch, based on your suggestions. Command queueing for controller is now much simpler; it's being enabled with dm_throttle_hw_controller() and disabled with dm_flush_hw_controller().
Simpler logic and less error prone.
Tested here on an SGI TP9500.
Cheers,
Hannes
