For the failover command I am currently hardcoding the format in the path-selector.
This seems like such a waste becuase if you look at sg io code (block/scsi_ioctl.c
for example), you can just pass in the command you want to execute. Is there any way
I could pass in such a thing when my target is created, so that way dm multipath
would not have any type of command format functions/modules or definitions
(it could just be passed in and built like the sg io code).
