The ctree (checksummed btree is really what it stands for) code itself is pretty basic. Aside from the checksumming, it is a simple btree with generation numbers to find the nodes that have changed since a given transaction. In terms of interesting/new code that others might want look at, the btrfs tree logging to do fsync efficiently (tree-log.c) and device management (volumes.c) are probably the most interesting. -chris _______________________________________________ users mailing list [email protected] https://www.nilfs.org/mailman/listinfo/users
