[dm-devel] Extending DM w/ new target type

two questions:
1. I'd like to use DM with a new target type. I'm porting our virtualized
storage solution from Windows. I've been able to register my target and
get callbacks working, but in looking at the dm-raid code, I'm concerned
with how tightly coupled it is with the routines in md.c (multiple devices
implementation). Is there an expectation that a DM target use the md_xxxx
routines?
2. I used dmsetup to create a mapping for a device that my target
controls. Is there a way to make the underlying device (e.g. /dev/sdb) not
visible to the system? I'm paranoid about external accesses to a LUN that
I'm using.
