Hi all, this patchset adds some more abstraction to the multipath hardware handlers. - A generic workqueue framework is added, which allows the hardware handler to submit failover commands independent from multipath I/O. - The exsting RDAC hardware handler is converted to use that framework - A new SPC-3 ALUA hardware handler is added, using that framework - A controller abstraction is added to the framework, which allows for command throttling based on the used controller. - The RDAC hardware handler is modified to use the new controller framework. This patchset superseded my previous implementation of the SPC-3 ALUA handler. Next plans are to update the table definitions and multipath-tools to allow for a passing of the controller ID from userland; ALUA doesn't specify for any controller information, so we have to do this by hand based on prior knowledge of the storage array. As per normal, comments etc welcome.
