Subject: [RFC] [PATCH] dm-cow: copy-on-write stackable target for device-mapper

This is the first cut of a device-mapper target which allows stacking of
multiple block devices and in which the top-layer of the stack is a
copy-on-write layer.  It was originally developed in support of a cluster
image management solution.


The paper describing our motivation for this work including some
description of this implementation and performance results is now
available:
