Aha! This needs to be applied on the top of your 'misc trivial cleanups' 
set.

The last time I've tried to introduce job control to the storage driver, 
it got rejected as it duplicated a lot of code from the qemu driver. 
Somebody suggested to rip the job control out into a separate unit so 
the code could be shared. Having said that, I'll review the patches, but 
please take my ACKs as 'code is okay' not permission to push. I'd rather 
see somebody else giving ACK to the design.
