Thanks, Yes, but it'd be a lot of work :) Change log-writes so that instead of replaying the log, you have it create a block device representing that specific point in the log - and then service read requests by looking them up however you like. So, it'd be just like mounting snapshots. It might not be too difficult since we can deal with crappy performance or memory usage here, but I don't know if it's really worth the effort. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
