[dm-devel] [PATCH 0/4] add manual failover support for HP storage works

[Mike Christie <michaelc cs wisc edu>]

mpath-init-cleanup.patch - just some cleanup from my last patches. It should 
applied on top of them.

hp-sw-init.patch - this is a priority-group module for the HP storage works 
device. I have only tested this with scsi_debug, so I know that the start_stop 
is making its way to scsi and is returning safely.
