[dm-devel] Integrating new DM targets to LVM

[Gili B]

Thanks
We are working on a module that creates 2 target types :
X_pool , X_Volume
 
The pool linkes together a list of disks and enables allocating volumes.
The pool device doesnt enable io , it's size is 1 sector and its map method is basiclly 
like dm_zero.
 
The volume's map io, generates new ios to certain devices from the pool according to the
pool's logic.
 
The intention is to implement logic which is optimized for SSDs, but the pool will be able to work with
normal disks, except it's performance won't be that good.
 
Thanks
