[dm-devel] [Resend] [PATCH 3/3] multipath: implement controller framework for hardware handlers

[Hannes Reinecke <hare suse de>]

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
