My mini-scsi-core does exactly that. Moving commands between queues is atomic.
The whole thing is completely reentrant and multithreaded capable, etc, etc.
It has a simple interface of send_command() and cancel_command(); doesn't have
device discovery though.
I tried to sell those features/ideas to SCSI Core, but we're not there yet.
Oh, I forgot to mention in my previous by date letter:
The entity which calls scsi_register_host() should by good design call
scsi_unregister_host(). It may be the case that when there are no
more devices associated with a particular host, then SCSI Core can
call scsi_unregister_host(), reminicent of SCSI Core early initialization.
