Hmm, I don't think scsi_target uses the clone API. Yes, probably it 
should or at least it will be better, but the problem will remain. From 
what I've understood we cannot call destroy_dev directly from d_close. 
The solutions I see are:
- use the destroy_dev_sched function posted by Kostik
- remove the device externally, after closing it (like other clonable
   devices already do)
The latter approach probably needs some redesign of the scsi_target 
code, while the first should be simpler if it works as expected (perhaps 
we should handle in a different way an open() to a closed but not 
already destroyed device, dunno).

Thanks for your support. I'm available to help (as much as I'm able) 
and test patches.
