+config COWLOOP
+ tristate "copy-on-write pseudo Block Driver"
+ depends on BLOCK
+ default n
+ ---help---
+ Cowloop is a "copy-on-write" pseudo block driver. It can be
+ stacked on top of a "real" block driver, and catches all write
+ operations on their way from the file systems layer above to
+ the real driver below, effectively shielding the lower driver
+ from those write accesses. The requests are then diverted to
+ an ordinary file, located somewhere else (configurable). Later
+ read requests are checked to see whether they can be serviced
+ by the "real" block driver below, or must be pulled in from
+ the diverted location. More information and userspace tools to
+ use the driver are on the project's website
+ http://www.ATComputing.nl/cowloop/
