[RFC] Log-structured File System for Linux that Supports Snapshots

[Pradeep Padala <ppadala@eecs.umich.edu>]

Hello,
    For past two months, I have been working on developing a 
log-structured file system (LFS) that supports snapshots as a part of 
the Google Summer of Code (SoC) [1] program. The motivation and goals 
for the project are described in my SoC proposal [2].
    In the current state, LFS is quite usable (all the basic fs 
operations are working), and a working cleaner is also available. 
However, it's not yet ready for the heavy iron and I need to sort out a 
few issues. I hope to include it in the mainline, and I will release a 
set of patches later for reviewing.
    Instructions on compiling and using the stable and development 
versions from CVS are available at [3]. The bleeding edge version 
includes basic snapshotting framework.
    The project website is http://logfs.sourceforge.net, and a mailing 
list [4] is available for discussion.
    Comments are welcome.

Thanks,
