Hi, It's been almost a year that nilfs2 has been merged into mainline kernel since 2.6.30, which is released in Jun 2009. Yet, it still shows warnings that "The NILFS on-disk format may change at any time". It still remains controversial argument, like directory indexing or atime support, xattr support and so on. However, I'd like to make the target clear that when the above message can be taken away. By fixing disk format, we might go forward to contribute more useful disk utilities like GNU pared. Some of those user land utilities require just reading super block (or blocks) to identify what the filesystem is in the specified partition. Therefore it would be good starting point to declare superblock format which ensure that upper/lower compatibilities. In addition to superblock format, over all disk format must be fixed somehow everybody thinks "it's ok". There are many features in ToDo list of nilfs web site http://www.nilfs.org/en/current_status.html. I can not tell which features should be in the nilfs2 before disk format fix as a modern mature filesystem, but I can tell not all of those are required :). Which of those do you guys think are the mandatory for modern filesystem and which may require disk format change? We might able to find consensus among the list before any modifying/fixing disk format.
