[linux-lvm] Snapshot rollback

[Eric Brunson <brunson brunson com>]

I remember seeing somewhere discussion of adding the ability to roll 
back to a snapshot.  I think of how cool this would be about ever six 
months, usually coinciding with an impending Fedora release.  ;-)

I know it's possible to copy the snapshot to restore the data, but what 
would it take to simply "abandon" the modified blocks and revert the 
volume to the snapshot state?  Is it being worked on?  Can I help?

Thanks,
