The goal of the dtfs project is to implement a log-structured file system within the Linux 2.2.x kernels. dtfs has a filesystem-independent core that provides general services required for a log-structured file system and uses a "traditional" file system implementation to do the actual filesystem/VFS operations. The tradtional file system of choice is currently Linux' ext2 file system. Using the ext2 file system together with the log-structured core should both reduce the implementation work required to be done and facilitate the future maintainence of dtfs.
